vah264enc: Fix caps for mesa gallium.

Browse source 
Radeon mesa gallium driver has a bug which adds P010_10LE sink caps
format. This patch removes formats which arent 420 chroma.

gst_caps_set_format_array() wasn't used because the fix traverse
several structures with potential different formats.
