tools include UAPI: Sync linux/mount.h copy with the kernel sources
To pick the changes from:
6ac392815628f317 ("fs: allow to mount beneath top mount")
That, after a fix to the move_mount_flags.sh script, harvests the new
MOVE_MOUNT_BENEATH move_mount flag:
$ tools/perf/trace/beauty/move_mount_flags.sh > before
$ cp include/uapi/linux/mount.h tools/include/uapi/linux/mount.h
$ tools/perf/trace/beauty/move_mount_flags.sh > after
$

That will then be properly decoded when used in tools like:
# perf trace -e move_mount
This addresses this perf build warning:
