vgaarb: fix "target=default" passing
Commit 77c1ff3982c6b36961725dd19e872a1c07df7f3b 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".
