[Mesa-stable] [PATCH v4] loader: add special logic to distinguish nouveau from nouveau_vieux

There are a lot of different pci ids supported by nouveau, and more are
added all the time. The relevant distinguisher between drivers is the
chipset id.

This has, again, been tested on NV96 and NV05.
v3 -> v4:
- remove is_nouveau predicate, move nouveau_vieux above it; this should
ensure that nouveau is treated as similarly as possible to how it was
before.
- remove extraneous includes left over from older code.
v2 -> v3:
- move dri2 auth before getting driver name
- fix nouveau ioctl params
v1 -> v2:
- add predicates that check for chipset
