The test and dist CI jobs run wrap the meson calls in dbus-runner to
avoid setting up dbus servers and mocking services for every test but
the dbus-runner invocation from meson test didn't actually skip all the
setup.
This nested mocking also doesn't work because the system bus is assumed
to be the host system bus and not a mocked one.

This means one can run meta-dbus-runner.py effectively mocking
everything relevant except logind itself, meaning one can run from a TTY
and get permission to mode set etc, while still mocking things like
gsd-color, colord, etc.

Real time scheduling is needed for better control of when we commit
updates to the kernel, so add a property to MetaThread that, if the
thread implementation uses a kernel thread and not a user thread, RTKit
is asked to make the thread real time scheduled using the maximum
priority allowed.
Currently RTKit doesn't support the GetAll() D-Bus properties method, so
some fall back code is added, as GDBusProxy depends on GetAll() working
to make the cached properties up to date. Once
https://github.com/heftig/rtkit/pull/30 lands and becomes widely
available in distributions, the work around can be dropped.

The D-Bus runner used by tests, including installed tests, is made to be
reusable from GNOME Shell. To do this, install it and the templates in
the pkgdatadir (e.g. /usr/share/mutter-APIVERSION/tests/), generate a
custom runner for the installed tests that uses the installed script and
templates, and change the non-installed original runner to use the
non-installed templates.
The end goal is to reuse the D-Bus session runner and templates used for
mutter when test running GNOME Shell.
