Use utf-8-unix for coding system conversions in the module API.

Factor out conversions into helper functions to provide a simpler
interface.

* src/emacs-module.c (module_encode, module_decode_copy): New helper
functions.
(module_make_function, module_copy_string_contents)
(module_make_string): Use them.
