xfree86: add per major-version driver/module subdirectories 

Modules are now placed into a sub-directory by major Xserver release,
so we have less hassle with trying to load drivers w/ incompatible ABI.

The legacy directories are still searched (after the versioned ones)
for backwards compat with badly maintained proprietary drivers (Nvidia).
