Some changes for better use of postinstall_helpers and run_stuff_*.

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.
