selftests/net: in timestamping, strncpy needs to preserve null byte
If user passed an interface option longer than 15 characters, then
device.ifr_name and hwtstamp.ifr_name became non-null-terminated
strings. The compiler warned about this:
timestamping.c:353:2: warning: ‘strncpy’ specified bound 16 equals \
destination size [-Wstringop-truncation]
353 | strncpy(device.ifr_name, interface, sizeof(device.ifr_name));
Fixes: cb9eff097831 ("net: new user space API for time stamping of incoming and outgoing packets")
