Added three new helpers to be used by packages requiring GTK+ and

by pango itself.

To be able to run those helpers once the package has been stowned
properly, another variable available for templates has been added:
"postinstall_helpers".

This accepts a list of template helper names, e.g:

postinstall_helpers="gtk-update-gdkpixbufloaders.sh gtk-update-immodules.sh".

Also rather than setting extract_cmd itself in pkgfs.sh when
extract_sufx=".zip", set it in the helper itself.
