This fixes the definition of the emulator-specific egl.cfg file
used to indicate to our EGL system library which support modules
are available in the emulator.
We need to list two modules here:
'emulation' corresponding to GPU emulation
'android' corresponding to the software renderer
The indices before each name correspond to the 'display' and 'impl'
numbers that are expected by frameworks/base/opengl/libs/EGL/Loader.cpp
In a nutshell, 'display' should always be 0, and 'impl' should be 0
for the software renderer, and 1 for a hardware-based one. See the code
under framewors/base/opengl/libs/EGL/egl.cpp for mode details.
