Alexander Morozov 993cbf9db0 move from Godeps to vndr
This uses the standard go vendor location instead of old Godeps
location.

Also remove usage of symlink GOPATH. Since our README mentions that you
should build it inside GOPATH, i think its a reasonable to assume that
you dont need to create a tmp GOPATH.
