For a mounted file system which is read-only, when
doing the MNT_RELOAD, pass in "ro" and "update"
string mount options to nmount() instead of MNT_RDONLY and MNT_UPDATE flags.

Due to the complexity of the mount parsing code especially
with respect to the root file system, passing in MNT_RDONLY and MNT_UPDATE
flags would do weird things and would cause fsck to convert the root
file system from a read-only mount to read-write.

To test:
 - boot into single user mode
 - show mounted file systems with: mount
 - root file system should be mounted read-only
 - fsck /
 - show mounted file systems with: mount
 - root file system should still be mounted read-only
