mxf distinguishes codec profiles by different UIDs and therefore needs to check that the input is actually compatible with mxf (i.e. if there is a defined UID for it). If not, then sometimes the UID would be set to NULL and writing the (video) packet would fail. Yet the following audio packet would trigger writing the header (which has been postponed because the UID is not known at the start) and if the UID is NULL, this can lead to segfaults. This commit therefore stops setting the UID to NULL if the input is incompatible with mxf (it has initially been set to a generic value in mxf_write_header()). Fixes #7993.
