Revert "Sensor: Add RotationVectorSensor2"

The implementation does not work as-is and the latest version of
Google Maps no longer needs it.

This reverts commit 45c5aa0ce71904ad8b00d5eba0627770b35b03ab.

Change-Id: I89b3730e93eb774dc2b9dace645d08cbfb311647
add BoardConfig flag TARGET_USES_OPENGLES_FOR_SCREEN_CAPTURE

This flag forces usage flags:
GRALLOC_USAGE_HW_TEXTURE and GRALLOC_USAGE_HW_RENDERER
in captureScreenImplLocked regardless of useReadPixels value

This fixes the EGL_NO_IMAGE_KHR error returned from
eglCreateImageKHR (blank images returned from screenshot path)
