This test is time sensitive. It may fail on virtual machines and for
debug builds.
Similar to commit c41dfb0dfbec ("selftests/net: ignore timing errors in
so_txtime if KSFT_MACHINE_SLOW"), optionally suppress failure for timing
errors (only).

`cur64`, `start64` and `ts_delta` are int64_t. Change format
specifiers in fprintf from `"%lu"` to `"%" PRId64` to adapt
to 32-bit and 64-bit systems.

PACKET_TX_TIMESTAMP is defined in if_packet.h but it is not included in
test. Include it instead of <netpacket/packet.h> otherwise the error of
redefinition arrives.
Also fix the compiler warning about ambiguous control flow by adding
explicit braces.

The txtimestamp selftest sets a fixed 500us tolerance. This value was
arrived at experimentally. Some platforms have higher variances. Make
this adjustable by adding the following flag:
-t N: tolerance (usec) for timestamp validation.

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