gnome.post_install does not support `update-mime-database`

Describe the bug
I am trying to migrate a custom post install script to gnome.post_install, but as far as I can see it does not provide a way to update the mime db.

My post install script does:

    subprocess.call(['glib-compile-schemas',
                    os.path.join(datadir, 'glib-2.0', 'schemas')])
    subprocess.call(['gtk-update-icon-cache', '-qtf',
                    os.path.join(datadir, 'icons', 'hicolor')])
    subprocess.call(['update-desktop-database', '-q',
                    os.path.join(datadir, 'applications')])
    subprocess.call(['update-mime-database',
                    os.path.join(datadir, 'mime')])

The last step is not provided by the gnome module

You can use meson.add_install_script('update-mime-database, prefix / datadir / 'mime', skip_if_destdir: true). This doesn't require waiting for a new meson version.

Yeah, I mean I can keep the current script, no big deal. Just opened the CR so that it gets fixed eventually :)
