%go_generate_buildrequires can't work in current c9s because of golist is not in the PATH when bundled

So, if we want to build a package on C9S which uses %go_generate_buildrequires it fails because of missing golist.

This is because when it was decided to bundle golist in go-rpm-macros, the location of the golist binary was not fixed in all files, it is missing from rpm/gosymlink.deps and rpm/macros.d/macros.go-rpm.
