Fix output cleaner and tool invocation bugs found in v2.6 test run

- Add clockres and du to -accepteula list; both were dumping full EULA
  text into report output instead of actual clock/disk data
- Add NativeCommandError/CategoryInfo/FullyQualifiedErrorId filter to
  Convert-ToolOutput so 2>&1 stderr captures don't leak PS error
  formatting into tool output sections
- Fix autorunsc argument bug: -a consumed -c as its selection type
  (codecs only), leaving no CSV flag and triggering usage help text;
  changed to -c only (default logon entries, CSV format)
