efs: Remove EFS
The kernel EFS code has been unmaintained for over twenty years.
It was superseded on IRIX around thirty years ago. I haven't seen an
EFS filesystem in the wild since 1999. Userspace tools to read EFS
filesystems exist, such as https://github.com/jkbenaim/efsextract
There's no benefit to keeping this filesystem in the kernel, and it only
increases the maintenance burden for tree-wide changes.
