In workspace setups that have the source tree symlinked into GOPATH,
the `go list `command wouldn't recognize that we're technically within GOPATH,
because `pwd` doesn't look like it.

For example

	/home/user/go/src/github.com/ipfs/go-ipfs
	=> /home/user/go/ipfs/go-ipfs

produces the import path

	_/home/user/ipfs/go-ipfs/Godeps/_workspace/src/github.com/jbenet/go-random/random

which is not within GOPATH.

We get around this by using fully-qualified import paths instead:
starting in github.com/ipfs/go-ipfs/ instead of ./
