boot/module.nix: add timeout option

Browse source 
On desktop systems, it is convenient to have the timeout
at zero, and just spam space when trying to start
a previous generation. On servers however, it is preferable
to have some time to choose the generation, which is
quite convenient if you have to acess is remotely via a
web interface, which tend to be quite slow and unresponsive.

Set the boot loader's timeout. This is 0 by default, but preferably longer on remote servers to make switching to previous generations easier.
