make capi-media-vision.pc file correctly

[Issue type] : code cleanup

capi-media-vision.pc file should provide a list to installed packages and
linked libraries correctly.

Without this patch, packages and libraries can be added in capi-media-vision.pc
file even though they aren't enabled. This is definitely a bug.

So this patch makes sure only enabled packages and libraries are added
to the pc file correctly.
