net_tstamp: Add SIOCGHWTSTAMP ioctl to match SIOCSHWTSTAMP
SIOCSHWTSTAMP returns the real configuration to the application using it, but there is currently no way for any other application to find out the configuration non-destructively. Add a new ioctl for this, making it unprivileged. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
