common: include gvc/gvc.h in output.c

E.g. attach_attrs used in output.c is declared in lib/gvc/gvc.h.

This change is not strictly necessary since gvc/gvc.h is indirectly
included through common/render.h anyway, but a direct inclusion is
clearer and will avoid confusion when an upcoming commit removes a
duplicated declaration of attach_attrs from utils.h.
