    rc: make the 'linux' script explicitly load filesystem modules
    
    This removes a minor annoyance with Linux jails, where you often
    want linux_mounts_enable="NO", yet you want those filesystems
    available for mounting in jails; normally mount(8) would result
    in kernel automatically loading the KLD, but this doesn't work
    inside jails or chroots.
