Isolate the code paths that crash the event logger service on Windows 10 2004

advapi32:eventlog has at least 7 code paths that can crash the event log
service on Windows 10 2004. Just set the crash variable between 1 and 7 to
experiment with each case.

In all cases it seems to be the combination of BackupEventLogA() (such as in
create_backup()) followed by OpenBackupEventLogA(NULL, backup) that causes the
crash (replacing NULL with "" crashes too).

So essentially it's opening a backup that causes the crash.
