- redefine pmlogconf to exclude derived metrics, and have it set
  env PCP_DERIVED_CONFIG="" for itself / pmprobe


since derived metrics are never logged (they're defined client side only),
the above makes the most sense. This is akin to the call to the call to
__pmSetInternalState(PM_STATE_PMCS) in tools such as pmlogextract and other
places. Looks like there are few othertools that need to set this too.
