system: Add 'bootloader-menu-entries' field to <boot-parameters>.
This allows us to keep track of the extra menu entries specified in the OS configuration. * gnu/system.scm (<boot-parameters>)[bootloader-menu-entries]: New field. (read-boot-parameters): Initialize it. (operating-system-boot-parameters): Likewise. (operating-system-boot-parameters-file): Serialize it. * gnu/bootloader.scm (menu-entry->sexp, sexp->menu-entry): New procedures.
