Fix #79: Add 'nowait' option to tty setting, external getty

This patch makes it possible to disable the "Please press Enter" prompt
when using an external getty. Simply append `nowait` to the .conf entry
and Finit will spawn the getty immediately.

A future patch will add support for `noclear` as well to external getty,
as well as a change in default (=> `wait`) for the built-in getty.
