emulator/opengl: Remove obsolete directory.

All sources were moved to external/qemu/distrib/android-emugl
to make it easier to modify both the emulator and host libraries
at the same time. See:

    https://android-review.googlesource.com/#/c/118203/

As such, the sources in this directory are now ignored and can be
safely removed.
