    rc.d/jail: add legacy compatibility for zfs.dataset
    
    Evaluate the jail_${jailname}_zfs_dataset variable for legacy
    jail managers.
    
    This variable can take a space separated list of datasets.
    The singular was used specially to allow unmaintained jail
    managers like ezjail to use this (simply rename
    jail_${jailname}_zfs_datasets in the ezjail config to
    jail_${jailname}_zfs_dataset).
