build/boot/rom: only insert scan.cfg if needed

where it is set to "both" (grub_scan_disk), inserting
scan.cfg is superfluous, because grub.cfg defaults to
both anyway, unless otherwise specified by scan.cfg,
and only if that file exists within cbfs.

thus, save a bit of build time (only a slight saving)
