fix: hold the new profiles to the shared checks

BizHawk's NDS firmware slot accepts six dumps, two of which the collection holds, and the profile named one. Kega Fusion's US Mega CD BIOS covers the Americas. Sonic 3 A.I.R. data is installed by Batocera in unpacked form. izApple2 downloads its ProDOS images when a card is added, which is no install. The Lakka list now equals a case-keeping RetroArch install less what Lakka's packages install, and the profile hash contradiction count leaves out entries no pack ships. The pipeline table names step 8b.
