Implement a install_type and install_metatype

This prepares for the RHEL OSP implementation by making the build
tool convert all binary-* into an install_type of binary and * into
an install_metatype variable substitution inside the Dockerfiles.
Further binary-* is substituted as install_name to enable proper
building only.
