qemugl: Fix GL apps failure on Ubuntu 11 host with nVidia GLX driver

Previous version of nVidia GLX driver in Ubuntu 10 cause qemu segfault, so we
fall back to Mesa GLX driver if detecting nVidia driver installed. From Ubuntu
11, nVidia GLX driver works well, while previous work around cause GL apps
failure. So this work around is limited in Ubuntu 10 only, and will be removed
in future.

[YOCTO #1886] got fixed.
