Add acl freebsd (#3656)

* FreeBSD do not support --omit-header and --absolute-names

* The option for following symlink wth getfacl is different on FreeBSD

* ZFS on Freebsd use nfsv4 acls, who use a slightly different syntax

* FreeBSD do not have a --test flag, so always return 'True'

* FreeBSD do not have the --omit-headers options, so we have to filter by ourself

* Mark Freebsd as working for the acl module
