sysinstall/libdisk BARFs at STRIPE

[Sam Lawrance]

I have no idea what's going on in open_disk.c, but it barfs when it
encounters my geom stripe partition (t=STRIPE). No doubt there are other
unhandled providers.

Lukas, i noticed you added code to ignore geom vinum providers, so I
cc'ed.

Cheers
Sam.
