media/gpu/vaapi: Fix Lowpower encoder entrypoint check

crrev.com/c/2292780/ refactors profile support and added entrypoint check
in IsProfileSupported.Currently in IsLowPowerEncSupported function
all LP encoder supported profiles(kSupportedLowPowerEncodeProfiles) are
checked if it support VAEntrypointEncSliceLP and returns true if any
profile supports lp entrypoint.This Cl fixes lp encoder entrypoint check
and returns true only if va_profile(function argument) supports
VAEntrypointEncSliceLP.
