Fix ruby %alias directive for native c functions

Using the %alias directive on native C functions causes swig to segfault due to
a dereference of klass (which is NULL for native C functions) in the
defineAliases function of the Ruby module. This commit adds support for an alias
of native C functions for both separate module as well as global functions, as
well as three test cases for the %alias directive of the Ruby module.

Fixes:
mod.i
%module ruby_alias
%alias get_my_name "nickname,fullname";
%inline %{
const char *get_my_name(){
  return "Chester Tester";
}
%}
$ swig -ruby mod.i
Segmentation fault
