Make an Android-specific copy of Skia's Null GL interface
This functionality has been removed from Skia, but is still being used by HWUI's NullGlesDriver for unit tests. Making a local copy gets tests passing (so that rolling can resume). Test: hwui_unit_tests still pass Change-Id: I16b65af58eaeca5a39df89d1542760b652d8b0d5
