UNIXSocket.new should accept Path in addition to String

[BigBoyBarney]

Most methods that operate with filesystem paths accept both String and Path, like virtually everything in File.

UNIXSocket.new currently only takes String.

I assume this is because Path was added later and UNIXSocket wasn't changed to accommodate that. Would there be any problems with allowing Path too?

I don't see any reason why not. If you see any other places, please bring those up too, it'd be nice to get as many as possible at once.

For now I've only encountered UNIXSocket#new and UNIXSocket#open.

There's UNIXAddress too.
