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.
