h265parse: Add special profile case for profile_idc 0.
This is a work-around to identify some main profile streams having
wrong profile_idc. There are some wrongly encoded main profile streams
which doesn't have any of the profile_idc values mentioned in Annex-A,
instead, general_profile_idc has been set as zero and the
general_profile_compatibility_flag[general_profile_idc] is TRUE.
Assuming them as MAIN profile for now.
