fix: file every platform system under a known id

Thirty platform system ids, such as sufami, pokemini, vsmile, and
Recalbox's comma-joined msx1,msx2, matched no system any profile
names, so no core file was attributed to them and --system missed them.
The scraper maps now carry those names, and a test holds every platform
system to a profile system apart from two named folds.
