containers/storage needs math/bits which has been added in go 1.9, so
this is now the lowest possible go version to build skopeo. We can also
remove the GO15VENDOREXPERIMENT variable since this has been enabled in
go 1.6 per default and removed in go 1.7.

(skopeo copy) will soon ALWAYS require a present policy file. So,
install one by (make install), and ensure that integration tests do so
as well.
Also simplifies the usage of install(1) a bit.
So that people don't need to install all dependencies just to build.
Make it so that "make binary" does nothing if nothing changed.
Remove ${DEST}
