Need to include the selector.

I'm surprised - I thought this was okay because this is only used when
!skia_build_for_android_framework, so it made sense to me that we could pick the
one that is used under that condition.

Yeah this *should* be ok.

AFAICT, the issue is that (if we don't include the extra indirection),
gyp_to_android.py will attempt to parse libjpeg-turbo.gyp and will fail when
"host_os" is not defined.
