gops replacement for GoLand

GoLand needs gops utility to list all Go processes for debugger.

This utility is a replacement of a small subset used by GoLand, namely:

• GoLand invokes gops without arguments.
• GoLand reads the output, and ignores everything except first word (PID).

Why replacement

gops uses github.com/keybase/go-ps that uses cgo under macOS.

github.com/mitchellh/go-ps does not use cgo, but also does not have Path() method used by gops.

To avoid cgo we have to reimplement pieces of go-ps, unfortunately.
