system: Take kernel modules from the user-specified kernel.

Browse source 
* gnu/system/linux-initrd.scm (base-initrd): Add #:linux option to
  specify the linux kernel to use.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Propagate
  #:linux to base-initrd.
* gnu/system.scm (operating-system-initrd-file): Pass #:linux to
  'make-initrd'.
