Add first version of emacs-openrc

Ported from gentoo using a simplified version without emacs bin wrapper.
I need get some vars to put on defaults, like SHELL, HOME and USER. As
the service start as root and the final user is not him, I need do some
hacking here. Sorry for this shit :(

BTW, in some way, this works.
