[fs] use XDG_CACHE_HOME for shader caches (#4093)

makes it so the shader cache goes properly in `XDG_CACHE_HOME`.

SOME people have it set to point to `/tmp` AND as a ramdisk, if they can do that they probably would want their shader caches to be there as well and wouldnt mind the extra hit from invalidations on reboot.

afterall, its a cache, not some holy data that needs to be kept at all costs.
