tools include uapi: Sync linux/fs.h copy with the kernel sources

To get the changes in:

  e262e32 ("vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled")

That made the mount flags string table generator to switch to using
mount.h instead.

This silences the following perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/fs.h' differs from latest version at 'include/uapi/linux/fs.h'
  diff -u tools/include/uapi/linux/fs.h include/uapi/linux/fs.h
