stagefright: Use fallback color standards mapping for legacy HALs

FP2's legacy media HAL reports color standards differently than expected
by CTS, so that ColorUtils maps into extended standards when it
shouldn't. Use existing fallback mappings also to map from color aspects
to color standards to fix the mismatch.
