fix: re-profile dosbox_pure for its sc-55 driver

 Each file is checked the way your platform checks it. Most compare a checksum, the fingerprint of a file's contents, which catches a corrupt or unexpected copy. RetroArch, Lakka and RetroPie only look for the filename, because that is all their code does: the Coverage table says which applies to you. Independently of that, the collection records five fingerprints per file, and wherever an emulator's code states an expected size or hash, that value is read from its source and rechecked here.

 Each fraction is what the pack has over what is needed, counting required and optional files alike since both ship. The first column is the BIOS list the platform publishes. The second counts files its emulators load that this list never mentions, found by reading their source code, and it is routinely several times larger. A short fraction means files are still missing, and they are named in the [gap analysis](https://abdess.github.io/retrobios/gaps/).
 That second number is a floor, not a ceiling: an emulator that accepts any file handed to it names none in its code, so nothing there can be counted.
