guix system: Reinstalling the bootloader preserves extra menu entries. 

Fixes <https://bugs.gnu.org/36876>.
Reported by Jesse Gibbons <jgibbons2357@gmail.com>.

Previously 'guix system delete-generations' or 'switch-generation' would
lose the extra bootloader menu entries specified in the current system's
configuration.  This fixes that.

* guix/scripts/system.scm (reinstall-bootloader): Turn PARAMS into a
single <boot-parameters>.  Adjust ENTRIES to include extra menu entries
specified in PARAMS.
