Honor the property overrides for GLES.
One of the fundamental problems of the GLES loader is that we never take
ro.hardware.egl and ro.board.platform into account while we try to load the
system driver. As a result, if a device specify the naming via these two
properties, it will not work.
Checking these two properties will allow us to remove a bunch of checks as
well, eventually we want emulator and swiftshader to go through this approach
instead of having a bunch of checks.
Another issue, is that the final loading of the system graphics driver will
load from whatever that match the wildcards of libGLES_*.so or [libEGL_*.so,
libGLESv1_CM_*.so, libGLESv2_*.so]. This is bad, for example, on cuttlefish,
there could be multiple system drivers exist at the same time and cuttlefish
can set ro.hardware.egl during boot time, however, when the graphics driver
fails to load, it will silently load other graphics driver via wildcards
matching. We want to make sure that once the loader fails to load the graphics
driver using system properties, the device can't boot.
In this patch, we attempt to load the system graphics driver by appending these
two properties at the end of the graphics driver library names before we start
to load from the exact names of the graphics driver, and remove the wildcards
matching.
