hwdb: run "update-hwdb"

As usual, it seems to be mostly additions and corrections. Sadly, it seems a
bit of mojibake has crept in in various places. But it's hard to correct, in
particular because it's hard to detect all cases automatically. I think we can
ignore this for now.

When I run this a few weeks ago, ma-large.txt was gutted and 20-OUI.hwdb was
siginificantly smaller. For whatever reasons, it's back to normal now.
