Do not directly link to EGL/GLESv2 for arm x11 chromeos

Do not directly link to EGL/GLESv2 for arm x11 chromeos

Chrome will already link to EGL/GLES if/when it needs to.
We need not explicitly set these libraries via link settings.

This works around the fact that the chromeos arm-generic board does not
currently use EGL/GLES.  It uses GLX and OpenGL as provided by mesa's
xlib-glx.  In order to satisfy these hard coded -lEGL -lGLES linker
settings, arm-generic was forced to build a dummy EGL/GLES implementation.
Without these link settings, we can remove the dummy opengles.
