Expose #:pre-mount argument of boot-system to raw-initrd.

[Hilton Chain]

Hi Guix,

This patch adds a #:pre-mount argument to raw-initrd, to be used in the later
boot-system invocation. This enables more customization space while avoiding
raw-initrd definition duplicates.

My main goal is to unlock LUKS root partition remotely via SSH, as in the
NixOS module linked below:
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/system/boot/luksroot.nix

I'm stilling experimenting with that, further progress would come as replies.

Thanks!
