ntp: add deterministic support for KPPS interface
ntp checks for presence of sys/timepps.h to determine whether the kernel
supports the RFC 2783 KPPS interface. Under Linux the pps-tools package
installs this header. Without this feature the ATOM clock driver does
not work, and other drivers like NMEA have reduced precision. Remove
the feature non-determinism and increase ntpd capabilities by adding an
explicit dependency.
See: http://doc.ntp.org/4.2.6/kernpps.html
