Allow current host in peers (#25)

There are legitimate cases where one might want to use the current host
in "peers". In particular our tests do this by using "localhost"; this
*usually* works because the hostname returned by `gethostname` is the
~unique name of the host, so doesn't match "localhost".

In some environments, though, `gethostname` can return "localhost",
which causes the peer to get filtered out. Notably this includes nix
build environments, which intentionally avoid letting global unique
state into the environment, since it would make the build
non-reproducible.
