libgles-omap3: work around bug in opkg

All the EGL_BADALLOC failures that user have been reporting turn out to be
a bug in opkg:
http://groups.google.com/group/opkg-devel/browse_thread/thread/741d18b0ef31435e#

Opkg decides to relink symlinks to the wrong files. As a workaround we check
the symlink during every bootup and fix it if needed.
