fix: keep recalbox composite md5 on archives

Bios.cpp:64-68 hashes a .zip with Zip::Md5Composite, the md5 of its
members in name order. A profile's md5 on an archive is the container's,
so it neither pairs with, corrects nor fills that field, and an archive
addition with only a container md5 is left out.
