tools include UAPI: Update linux/mount.h copy

To pick the changes from:

  9ffb14ef61bab83f ("move_mount: allow to add a mount into an existing group")

That ends up adding support for the new MOVE_MOUNT_SET_GROUP move_mount
flag.

  $

So now one can use it in --filter expressions for tracepoints.

This silences this perf build warnings:
