libsemanage: Add Ruby Bindings

This patch adds a SWIG specification file for ruby bindings for libsemanage.
The spec file is almost identical to the python SWIG file with the exception
that all list generating typemaps have been removed and the python related
functions have been replaced with the corresponding ruby ones. Finally the
Makefile is modified to be able to build the new bindings. Something to note is
that on 64-bit systems ruby.h might be found somewhere under /usr/lib64 instead
of /usr/lib so LIBDIR=/usr/lib64 will be needed to build the ruby bindings from
source.

Below is an example using the ruby bindings and produces the similar output
to semodule -l

#!/usr/bin/ruby
require "semanage"

handle = Semanage.semanage_handle_create

Semanage.semanage_select_store(handle, "targeted", Semanage::SEMANAGE_CON_DIRECT)
Semanage.semanage_connect(handle)
module_info = Semanage.semanage_module_list(handle)

modules = Array.new()
module_info[2].times do |n|
        temp_module = Semanage.semanage_module_list_nth(module_info[1], n)
        mod_string = Semanage.semanage_module_get_name(temp_module).to_s + " " \
                        + Semanage.semanage_module_get_version(temp_module).to_s
        modules.push(mod_string)
end

        puts "List of Installed Modules"
modules.each do |str|
        puts str
end
