mkosi: Add --quiet and --no-rebuild options to meson install in mkosi.build

By default, meson install prints a line for every file it installs.
This is verbose and doesn't provide much value. Let's silence the
meson install step to remove this output from the mkosi build step.

The --no-rebuild option removes some additional duplicate output
by the meson install step.

Ubuntu Focal still has meson 0.53.0 so we add a version check and
only use the new feature if the meson version supports it.
