Subject: [PATCH] Adds service.emacs.exec to choose emacs binary to execute

The motivation of the change is that some forks (ie. Wilfred/remacs)
choose not to use the emacs binary. Whereas it is perfectly possible
to generate /bin/emacs in a drv, but I strongly believe it's cleaner
to have a service parameter.
