Wrong loader path defined in pkgconfig

[Sebastien Bacher]

* Impact

The .pc references to a wrong location for the loaders binary. That's because the file is moved from the packaging .install which the build system doesn't know about.

* Testcase

$ pkg-config --variable=gdk_pixbuf_query_loaders gdk-pixbuf-2.0

should return '/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders' matching where the file is installed

* What could go wrong

The change is only patching the .pc there is no code change. If the patch was wrong the path returned could still not match the actual binary location
