Don't allow the NTP support and asynchronous name resolving to be disabled. pthreads are now a hard requirement. NTP is the primary task of chrony. This functionality doesn't seem to be commonly disabled (allowing only refclocks and manual input). This removes rarely (if ever) used code and simplifies testing.
