94e05f7f28 gio-launch-desktop: Only replace fds that point to the Journal
If stdout is the Journal but stderr is not, then we probably only want
to redirect stdout, or vice versa.

763643ceaa gio-launch-desktop: Redirect stdout, stderr to systemd Journal
This prevents a launched process's output from being mixed up with the
output of the parent process, which can lead to the wrong program being
blamed for warning messages.

d0967c1d4a Revert "gdesktopappinfo: Use sh rather than gio-launch-desktop"
A shell one-liner was enough to set GIO_LAUNCHED_DESKTOP_FILE_PID,
but ideally we also want to do the equivalent of sd_journal_stream_fd()
to set up its standard output and standard error streams.

Ideally we would call sd_journal_stream_fd() in a process that will
exec the real program, otherwise it will report the wrong process ID
in the Journal, but we can't easily do that in a forked child when
using posix_spawn() for subprocesses.

This reverts commit 2b533ca99a.

2b533ca99a gdesktopappinfo: Use sh rather than gio-launch-desktop
There were some problems about where to install `gio-launch-desktop` to
support multiarch systems without circular dependencies. Simon McVittie
suggested that, actually, given the current set of platforms supported
by `GDesktopAppInfo` (they’re all POSIX), we could just use `sh`.

That simplifies things nicely. `gio-launch-desktop` can always be
resurrected (and the multiarch debate continued and resolved) if needed
in future.

742efe6232 gdesktopappinfo: enable fast posix_spawn gspawn codepath
In order to use the new posix_spawn gspawn codepath, for more robust
app launching when available memory is low, we need to meet some
conditions.

child_setup needs to be NULL for this optimization to work, so drop
the internal child_setup that is used here. Replace it with a lightweight
wrapper binary (gio-launch-desktop) that sets GIO_LAUNCHED_DESKTOP_FILE_PID
before executing the app.

Adjust PATH for gio tests so that it can execute the new binary from the
build directory.
