Revert "Load native GLES driver when specified."

Original commit message:
"""
Load native GLES driver when specified.

Since ANGLE and native GLES drivers can coexist, when native is
specified, the loader must load the native GLES drivers specified in
ro.hardware.egl. This patch adds the support to load native GLES drivers
when specified.
