i915: Handle the case where legacy mmap is not available, v2.

We will remove support for the legacy mmap ioctl, so handle that
case without rewriting all tests.

When the gem_mmap ioctl is not available, transparently fallback to mmap_offset.

Changes since v1:
- Skip gem_tiled_wc too, as it requires on legacy mmap behavior. (Ashutosh)
- Remove fallback for __gem_mmap__gtt, it's already mmap_offset. (Ashutosh)
