nvh264enc: Fix broken Y444 format encoding with system memory Y444 support

Browse source 
separateColourPlaneFlag is mapped to separate_colour_plane_flag which
means Y, U and V planes are separately processed as monochrome sampled pictures.
So encoder shouldn't set that flag for normal 4:4:4 encoding.

Also for 4:4:4 encoding, NV_ENC_H264_PROFILE_HIGH_444_GUID profile must be
explicitly set.
