PATCH: complete services in _fuser

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

The psmisc (Linux) version of fuser can take network services as a
parameter, showing processes with network connections open. This patch
makes _fuser handle that. You need to be root for it to work so unless
'-n tcp' is specified, it doesn't affect completion for non root users.
