selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET

Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional
digits, therefore leading zeros are meaningful.

This patch changes the format strings to "%lld.%09u" in order to add
leading zeros to the nanosecond value.

Fixes: 4ec54f95736f ("ptp: Fix compiler warnings in the testptp utility")
Fixes: 6ab0e475f1f3 ("Documentation: fix misc. warnings")
