refactor: drop dead mount_efi and select_raid_level from lib/disk.sh

lib/disk.sh:mount_efi() was shadowed by installer/archangel:mount_efi()
(different signature, no-arg ZFS-specific) and had zero callers.
lib/disk.sh:select_raid_level() was superseded by get_raid_level() in
archangel and also had zero callers. Both removed.
