Migrates from the deprecated toGNUCommandLineShell to toCommandLineShellGNU.
This changes the output format from space-separated short options
(-t 3500) to concatenated GNU-style options (-t3500). Both formats

As per systemd.special(7)[0] graphical-session-pre.target is strictly
for units that set up things for a graphical session. Most notably,
these are usually started *before* the compositor/session is actually
ready.
While Home Manager's current implementation of graphical-session.target
allows these units to work regardless of what systemd.special(7)
specifies, other setups like ones with uwsm[1] do not allow these units
to start properly.

This option provides a more convenient way to overlay dummy packages.
It also adds a function `config.lib.test.mkStubPackage` that can,
e.g., be used for `package` options.
