Check ntp time delay (#2277)HEADmaster

* check_ntp_time: add polling delay

NTP server can have rate limiting which might be triggered by
check_ntp_time due to many requests in a short time span.

This patch adds a default delay (of 0.5s) between requests to each server
and a command line option (--poll-delay) to make this delay
configurable.

* check_ntp_time: verify whether socket path fits into address struct

check_ntp_time could be give a too long (>108 bytes) socket path
to work with, which would potentially crash the program.
This patch validates to length beforehand and stops execution
in that case.
