fix: drop names DraStic never opens

DraStic opens nds_bios_arm9.bin, nds_bios_arm7.bin and nds_firmware.bin and checks their size. Its nine aliases are in none of its binaries, and neither platform launcher passes them: ROCKNIX links the two BIOS names from its bios folder, and RetroPie runs DraStic from $md_conf_root/nds/drastic (drastic.sh:48), now a passes_path record. The collection answers DraStic's names with its DS dumps in generate_db, where repository names belong.
