Must use make build in spec file to build ginkgo

The OS_OUTPUT_GOPATH value is only set by the makefile, and an RPM build
environment won't have it set otherwise. This resulted in the RPM build
failing because the GOPATH didn't match the repo.

Include a requires against openssl-devel to support use of packaged
versions of golang that don't take the dependency properly.
