gio-module-cache: Add class for Gio modules

The new class uses gio-querymodules tool on postinst and postrm.
This regenerates the module cache which is useful to avoid loading
modules that are not needed at runtime: If a Gio module is not
listed in the cache file it will always get loaded.

* Add a postinst-intercept 'gio-module-cache': it runs
  gio-querymodules using qemuwrapper. This is required because the tool
  actually loads the modules to generate the cache.
* Add a gio-module-cache class that adds postinstall and postrm
  scripts. In the sysroot population case use the new intercept.
* Inherit the new class in glib-2.0, glib-networking and gconf.

Fixes [YOCTO #9241].
