Fixes: Install gconf schemas on make install
Fixes: Install gconf schemas on make install

RevBy: Michael Hasselmann
Not installing the gconf schemas lead to a lot of problems for
consumers, as without the schemas, the uiserver does not run properly.

GCONF_DISABLE_MAKEFILE_SCHEMA_INSTALL=1 make install
can be used when packaging to skip the install. The packages
would instead use gconftool from post/pre install scripts.
