build: meson: Replace the 'test-target' argument by 'test-options'.

This change is motivated by the need to disable the default 30 seconds timeout
that Meson uses (see: https://gitlab.gnome.org/GNOME/glib/-/issues/2522), and
also by desire to specify extra options to run the check phase without having
to override it.

with...
<test-options>: ... this one.
* guix/build/meson-build-system.scm (check): Invoke 'meson test' instead of
'ninja test-target', as the former is configurable via options.
