New port: sysutils/acltool: cli tool to display & updating filesystem ACLs

This is a port of acltool, an ACL manipulation CLI tool.

This is a tool to manage NFSv4/ZFS/SMB (also known as Extended on MacOS)
style ACLs of filesystems. That is listing, creating, editing, searching,
stripping, sorting, removing redundant entries and more.
