libgles-omap3: add a guard in init script

urjaman reported install_lib()'s "rm /usr/lib/${baseso}*" somehow
destroyed his /usr/lib, so patch around empty ${baseso}. No idea how
exactly it happened though. Not bumping the version to not cause an
update, which will just bring risks without benefits.
