mount: allow [ro|rw|rq|sw|xx] as available mount options

[tschettervictor]

Allow and require at least on of the following strings inside the "options" string of mount.
rw
ro
rq
sw
xx
According to fstab documentation.

Testing
Mount files and directories into jail(s) with different combos of comma separated options, making sure one (and only one) of the above options are also present.

Example bastille mount jailname /host/path /jail/path nullfs rw,nosuid,mode=01777 0 0 or bastille mount jailname /host/path /jail/path nullfs nosuid,ro,mode=01777 0 0
