runqemu: fix fedora pkg names when run fails

runqemu can fail to with the following message:

    You need libGL.so and libGLU.so to exist in your library path to run the QEMU emulator.
        Fedora package names are: mesa-libGL mesa-libGLU.

The libGL.so and libGLU.so files are provided by the mesa-libGL-devel
and mesa-libGLU-devel Fedora packages (yum provides '*/libGL*.so').
