[0/2] statx NULL path support

Message

Generated against vfs/vfs.empty.path, uses the new vfs_empty_path
helper.

I had to revert "xattr: handle AT_EMPTY_PATH correctly" locally due to
compilation errors.

io_uring is only-compile tested at the moment, perhaps the author
(cc'ed) has a handy testcase for statx.

Note rebasing this against newer fs branches will result in a trivial
merge conflict due to later removed argument from getname_flags.

  vfs: add CLASS fd_raw
  vfs: support statx(..., NULL, AT_EMPTY_PATH, ...)
