liboping: use SO_TIMESTAMP when available

Current implementation of liboping relies on getting enough CPU shares
and getting those in a timely manner in order to determine correct ping
response times.

Avoid this limitation when kernel is able to provide packet reception
times using SO_TIMESTAMP. (as is done by iputils's ping utility)
