Introduce run_stuff_<state>_<stage>_cmd. These are used to run
a specific command before or after the specified stage.
Introduce two new helpers: fontconfig-update.sh and mkfontxx-rebuild.sh.
The first runs fc-cache once fontconfig is installed, the second
rebuilds the fonts.dir and fonts.scale files in a directory for
a template.
Allow run_stuff_* to execute a script with any path, not just
from PKGFS_TEMPLATESDIR.
That means that now if you install GTK+ and any fonts package,
gtk-demo will work without any additional stuff.
