vgaarb: fix "target=default" passing

Browse Source 
Commit 77c1ff3982 fixed the userspace
pointer dereference, but introduced another bug pointed out by Eugene Teo
in RH bug #564264. Instead of comparing the point we were at in the string,
we instead compared the beginning of the string to "default".
