plugin: drop explicit unlink
Go's `net` package [will unlink][1] for us, as long as we used Listen &
friends to create the Unix socket.

Go will even skip the unlink when the socket appears to be abstract
(starts with a NUL, represented by an @), though we must be cautious to
only create sockets with an abstract address on platforms that actually
support it -- this caused [several][2] [bugs][3] before.
