mid: add $MID_EXTRACT regexp for export

This allows us to consistently enforce the same Message-ID
extraction rules everywhere and makes it easier for us to
make changes in the future.

Update scripts/ssoma-replay, as well, but don't rely on
PublicInbox::* modules in that since it's legacy and
public-inbox was never a dependency of ssoma.
