Currently these mount options aren't accessible via statmount().
The read handler for /proc/#/mountinfo calls security_sb_show_options()
to emit the security options after emitting superblock flag options, but
before calling sb->s_op->show_options.
Have statmount_mnt_opts() call security_sb_show_options() before
calling ->show_options.
