Proposed fix for https://github.com/Neo23x0/sigma/issues/889
...
This change removes dns events from the network connection category. The
one change is that sysmon_regsvr32_network_activity.yml needs to test
the network connection category separately from the DNS event id.

For sysmon_hack_dumpert:
Make sure the logsource is category file_event and not sysmon. Don't set
the category at the global level. Instead set in the individual document.

To be consistent with the behaviour of the other rules, the eventID should not
be specified as part of the rule. The category defines the eventID.
