<menu-entry> entries.
* gnu/system.scm (menu->entry->boot-parameters): Delete variable.
(boot-parameters->menu-entry): New variable.  Export it.
(operating-system-bootcfg): Make OLD-ENTRIES a list of <menu-entry>.
* guix/script/system.scm (reinstall-bootloader): Fix bootcfg usage.
(perform-action): Fix bootcfg usage.
