vagrant / openbsd: use own box, fixes #1695

self-made basic openbsd box includes pre-installed rsync as vagrant is unable to install rsync.
as the self-made box now has enough space on /, remove workaround for low space.
delete line from tox.ini with sed so it does not try to install llfuse (which is broken on openbsd).
