Let check_ntp_peer check the number of truechimers

Add support for checking the number of usable time sources (i.e., the
number of peers which are classified as so-called "truechimers" by NTP's
intersection algorithm).  The new "-m" and "-n" options allow for
specifying the according WARNING and CRITICAL thresholds (and thereby
activating the truechimers check), respectively.
