Subject: [PATCH] blscfg: Don't attempt to sort by version if not present in
all BLS files
Commit a16805341cc ("blscfg: sort BLS entries by 'version' field") made to
sort by the version field take precedence over the BLS fragment file name.
But it also uses the lack of the version field in one BLS fragment as sort
criterion, which means that entries could be wrongly sorted if one of them
doesn't have a version field and others do.
So only sort by version if all the BLS entries have this field defined,
otherwise just fallback to sorting by the BLS file name.
