Modify all the similar Python test wrappers to set
`G_DEBUG=fatal-warnings` in the environment of the program being tested,
so we can catch unexpected warnings/criticals.
Adding this because I noticed it was missing, not because I noticed a
warning/critical was being ignored.

If the help output is explicitly requested by the user, it’s
conventional for it to be printed to stdout rather than stderr.

Store their details in an array which can be iterated over instead.
This introduces no functional changes, just a cleanup which will allow
following commits to be neater.

All the calls to `usage()` are immediately followed by a `return` from
`main()` which sets an appropriate exit status.
Calling `exit()` early means that running `gio --help` returns exit
status 1, which is incorrect — it should (by convention) return 0.

Depending on the operating system, /bin/sh might either be bash (for
example on Fedora or Arch) or dash (for example on Debian or Ubuntu)
or some other POSIX shell.
When bash is asked to run a simple command with no shell keywords or
metacharacters, like this one, it replaces itself with the program
via execve(), but dash does not have that optimization and treats it
like any other program invocation in a larger script: it will fork,
exec the program in the child, and wait for the child in the parent.
This seems like it conflicts with sleep_and_kill() assuming that it can
use the subprocess's process ID as the sleep(1) process ID. Specifically,
if it sends SIGKILL, it will go to the sh(1) process and not the sleep(1)
child, which could result in the sh(1) process being terminated and
its sleep(1) child being leaked.
To get the bash-like behaviour portably, explicitly use the exec builtin
to instruct the shell to replace itself with sleep(1), so that the
process ID previously used for the shell becomes the process ID of the
sleep process.
This appears to resolve an intermittent hang and test timeout on Debian
machines (especially slower ones), although I'm not 100% clear on the
mechanics of how it happens.

`test-generated.txt` is listed in `test.gresource.xml`, so it needs to
be specified as a dependency in the `custom_target()` which uses
`test.gresource.xml`.
Fixes intermittent build failures like:
```
FAILED: gio/tests/test.gresource

This reverts commit 0b9900e4e7.
The dependency was added in the wrong place: `test-generated.txt` is
needed when compiling `test.gresource`, not when compiling the test
which ultimately uses that gresource.
See !3671 and #3163.
The PTRACE_O_EXITKILL symbol in sys/ptrace.h is an enum member, not
a macro. The #ifdef check added to the GSubprocess test-case in
272ec5dbca will not detect it.
Use cc.has_header_symbol() to properly detect it. According to the
documentation: "Symbols here include function, variable, #define,
type definition, etc.".

On CHERI-enabled systems we use uintptr_t as the underlying storage for
GType and therefore casting to gsize strips the upper bits from a pointer.
Fix this by casting via uintptr_t instead and introduce a new set of
macros to convert between GType and pointers.
