Adding another test validated from the FreeBSD workflow.
Just because the keywords requested to be validated are not present in
the manifest, it is not an error.
Also, if the keywords from a new manifest are not present in a prior
manifest, then only compare the common keywords.
Fixes https://github.com/vbatts/go-mtree/issues/86

symlink(2) is a very dumb syscall, and allows you to put any damn value
you please inside a symlink. In addition, spaces are valid path
characters which causes issues with keyword parsing. So use Vis() and
Unvis() to safely store an encoded version of the path.
This also adds a cli test for this behaviour.
