g_get_user_database_entry() capitalises the first letter of pw_name
with g_ascii_toupper (pw->pw_name[0]).
However, the manpage for getpwnam() and getpwuid() says the result of
those calls "may point to a static area". GLib is then trying to edit
static memory which belongs to a shared library, so segfaults.
The reentrant variants of the above calls are supposed to fill the user
buffer supplied to them, however Michael Catanzaro also found a bug in
systemd where the data is not copied to the user buffer and still points
to static memory, resulting in the same sort of segfault. See:
https://github.com/systemd/systemd/issues/20679
Solve both these cases in GLib by copying pw_name off to a temporary
variable, set uppercase on that variable, and use the variable to join
into the desired string. Free the variable after it is no longer needed.

No need to call memset in the loop, we can just
initialize all the values in one go.
GtkBuilder is now using g_object_setv, so this
may improve application start times a bit.
Instead of calling xterm when it clearly does not exist and causes a silent error,
inform the user that the launch failed so they can take the right action.
If the first power-profile installed test fails (for example, because
xdg-desktop-portal isn’t available), correctly tear down the dbusmock
object, or it will cause setUp() to fail when the next test in the suite
is run.

When first creating the monitor, correctly set its property value to the
value from the portal, rather than waiting for the portal value to
change to set it.

We were lucky that this worked in some cases (the test is racy), but we
should actually run the condition check each loop, rather than when the
function is called.

The previous test was racy: it assumed that not all queued thread pool
jobs would start to be executed before `g_thread_pool_free()` was
called, whereas actually on some systems (particularly BSD ones), they
would all start (or even finish) being executed, and hence the free
function might never be called.
Rewrite the test to:
• Synchronise the test function and worker thread functions more
closely.
• Not bother about ordering the shared and exclusive variants of the
test differently. That seems to be a hangover from another test
above.
• Limit the number of worker threads to 1, rather than 2, since this
makes the test easier to control.
This has been tested with `--repeat 10000` on Linux, and it succeeds all
of those runs whereas previously it failed quite reliably.
