tests: improve vagrant usability

The first and most important change is to deal with the fact that
"localhost" is an IPv6 address in the vagrant box we're using.  This was
non-obviously behind some of the NFS tests failing to run properly, so
there's now an Ansible role etc. to make the necessary modifications in
/etc/hosts.  Also added "-j" to the make command, and changed the
invocation of "run-tests.sh" so it passes through any arguments instead
of running all tests every time.
