Patchwork gconf.bbclass: don't register schemas in the install stage

Previously this was installing schemas in the sysroot, which is wrong for native
packages as nothing should touch the sysroot directly, and even more wrong for
non-native packages as the sysroot is irrelevant.

So, export the environment variable that stops the registration happening at
install time. The postinst script will handle the non-native case, and for the
sysroot I've opened #2648.  This isn't a massive problem as nothing to my
knowledge actually installs schemas to the sysroot.

[YOCTO #2245]

Even better is to have the source code check for DESTDIR, and skip gconf
bits itself; e.g.:

http://git.gnome.org/browse/evolution/tree/shell/Makefile.am?h=gnome-2-28#n201

This patch is still useful though for components which don't check
DESTDIR, but again it's better to patch the relevant source code to do
so (or port to GSettings...).

I'd prefer to use an option that the GConf autoconf macro provides over patching every module that uses GConf, as we're assured much better coverage that way.  Adding the option caught every module in the Sato image but two, which were being rather minimal with their build system and the environment variable caught those (as it affects gconftool itself).

Merged into OE-Core - Still needs to be merged to 1.2.1

Thanks

I wasn't objecting to your patch.  However, please do *also* (in
addition, as well, etc. ;) ) consider patching these modules upstream.

Concretely doing so will also fix jhbuild (and my gnome-ostree build
system).
