Several fixes for sysmon rules got lost when the rules were refactored to use
categories.

Re-add the fixes.

Brad Kish 7e06fd80fd Proposed fix for sysmon_uac_bypass_eventvwr
Issue: https://github.com/Neo23x0/sigma/issues/888

The rules were not merged correctly with the transition to sysmon categories.

Split the rule into separate documents: one for the registry_event and one for
the process_creation

Brad Kish 8b3b312c4e 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.

Brad Kish 1e9d0e9653 Fixes for rules in the sysmon file_event category
Fix a couple of typos

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.

Brad Kish 4b31633355 Fixes for rules in new sysmon registry_event category
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.
