Update gin_integration_test.go (#2341)

* Update gin_integration_test.go

TestUnixSocket fails if you run it twice in a row.  This is due to the unix socket file persisting.  Added defer to clean up.

Whats unclear is the following test TestBadUnixSocket I suspect is just looking for cruft maybe from a prior test or defaults not working, I have not enough background to say.

* Update gin_integration_test.go

I believe there is some tab issue here, tried to manual overwrite it now.

* Update gin_integration_test.go
