UnixSocketConfiguration: Change from/to to source/destination

This is something I forgot to update ages ago. The field names,
while they do make sense, were different than the constructor
names that eventually set the fields themselves. This is kind of
awkward, and I'd much rather fix this now while it's much easier.
