net/ruby-ffi-rzmq-core: import ruby27-ffi-rzmq-core-1.0.7

The intention of this gem is to provide a very basic FFI wrapper
around the Zeromq libzmq C API. This gem isn't intended to be used
directly by any Ruby programmer looking to write Zeromq code. They
should use a higher-level gem like ffi-rzmq which pulls in this
gem for its FFI definitions.
