[PATCH] system: Avoid using device paths in <menu-entry> device field. |

From: Chris Marusich <address@hidden>
This fixes a regression introduced by
1ef8b72a7f87afe7cffe52393d99e1b14e4770e1, in which we would incorrectly use a
device path in a label-based grub root search command, e.g. 'search --label
--set /dev/sda4'.
* gnu/system.scm (grub-device): New procedure.
(operating-system-grub.cfg, operating-system-parameters-file): Use it.
(read-boot-parameters): Handle device paths correctly.
