test/get_create_config: test for packed headers special case

Driver should allow 0x0 (i.e. VA_ENC_PACKED_HEADER_NONE) value
for the VAConfigAttribEncPackedHeaders attribute during
vaCreateConfig when the attribute is supported.

This test supercedes intel/intel-vaapi-driver#361

Also see intel/intel-vaapi-driver#358 and intel/libva#178
