egl/android: #ifdef out flink name support

Maintaining both flink names and prime fd support which are provided by
2 different gralloc implementations is problematic because we have a
dependency on a specific gralloc implementation header.

This mostly disables the dependency on the gralloc implementation and
headers. The dependency on GRALLOC_MODULE_PERFORM_GET_DRM_FD remains for
now, but the definition is added locally to remove the header
dependency.

drm_gralloc support can be enabled by setting
BOARD_USES_DRM_GRALLOC=true in BoardConfig.mk.
