Remove hard-coded package url

[shicky]

Please remove hard-coded package url as it is not valid.

package selenium // import "sourcegraph.com/sourcegraph/go-selenium"

What makes you say it is not valid? GOPATH=/tmp go get sourcegraph.com/sourcegraph/go-selenium works for me. Does it not work for you?
