tools headers: Sync uapi/linux/fs.h with the kernel source

Browse Source 
To pick up the changes in this cset:

  76fdb7eb4e uapi: export PROCFS_ROOT_INO
  ca115d7e75 tree-wide: s/struct fileattr/struct file_kattr/g
  be7efb2d20 fs: introduce file_getattr and file_setattr syscalls
  9eb22f7fed fs: add ioctl to query metadata and protection info capabilities

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/uapi/linux/fs.h include/uapi/linux/fs.h

Please see tools/include/uapi/README for further details.
