This reverts two CLs

"compositor: Fix texture flipping for SW mirroring with surfaceless"
and
"Exclude reflector_impl_unittest.cc from GN non-Aura, non-Mac builds."

Reason for revert:
The original patch breaks software mirroring mode on at least veyron_jerry,
and quite possibly all non-freon systems.

>Original issue's descriptions:
>   Exclude reflector_impl_unittest.cc from GN non-Aura, non-Mac builds.
>    This fixes the GN build on Android after https://codereview.chromium.org/846063002.
>
>   (The GYP build didn't break because content/browser/compositor/ is completely excluded there; see https://code.google.com/p/chromium/codesearch#chromium/src/content/content_tests.gypi&sq=package:chromium&&type=cs&l=1099)

> compositor: Fix texture flipping for SW mirroring with surfaceless
>
> Ozone-surfaceless renders the scene flipped, so the texture contents are
> inverted from what they should be. This fixes the mirroring logic to
> un-flip the texture when needed, and also to send the right sub-buffer
> update rect.
