crrev.com/c/1982499 started passing NativePixmapHandles to the GL import
methods instead of raw DMAbuf FDs without layout information. But
creating a NativePixmapHandles involves duplicating the FDs of a frame ;
something that would fail on Tegra which passed invalid FDs that were to
be ignored during import.

Fix this by returning a dummy FD created from pipe() instead of an
invalid one. The dummy FD is not any more useful, but it can be
duplicated safely.

TEST=video_decode_accelerator_tests passing on nyan_big.
