v4l2object: Don't enforce dimension field on encoded formats

Don't enforce having width, height and framerate in template caps for encoded
formats. These don't always need to be exposed and may break negotiation for
decoder and decoding sink. If needed, these field will be automatically added
when probed caps are known.
