The timestamping tool is supporting now only PTPv1 (IEEE-1588 2002) while
modern HW often supports also/only PTPv2.
Hence timestamping tool is still useful for sanity testing of PTP drivers
HW timestamping capabilities it's reasonable to upstate it to support
PTPv2. This patch adds corresponding support which can be enabled by using
new parameter "PTPV2".

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));

For historical reasons, there are several timestamping selftest targets
in selftests/networking/timestamping. Move them to the standard
directory for networking tests: selftests/net.
