Yoann Lopes e48546b44f GStreamer: runtime check for controls that require GstPhotography.
Exposure, Flash, Focus and Locks controls were always initialized,
even when the GstPhotography interface was not available (on desktop
for example), causing some warnings and fooling the user in believing
that these features were available.
These controls are now lazily initialized and only when
GstPhotography is available.

The zoom control is not compile-checked anymore since it doesn't
actually require GstPhotography.
