mender: recreate full Go import path under GOPATH for build
mender: recreate full Go import path under GOPATH for build

Since commit a625568f4564dea0c4bcde009ef4157215e072cd, mender imports
its local modules (github.com/mendersoftware/mender/utils in this case).
For this to work, we need to recreate a complete GOPATH structure,
including github.com/mendersoftware/mender import path, for the build to
work.
