tools include UAPI: Update linux/mount.h copy
To pick the changes from:
  dab741e0e02bd3c4 ("Add a "nosymfollow" mount option.")
That ends up adding support for the new MS_NOSYMFOLLOW mount flag:

  $ cp include/uapi/linux/mount.h tools/include/uapi/linux/mount.h
  $ tools/perf/trace/beauty/mount_flags.sh > after

So now one can use it in --filter expressions for tracepoints.
This silences this perf build warnings:
