Miroslav Lichvar 69d3913f3e ntp: check timestamping configuration when SIOCSHWTSTAMP fails ...

With future kernels it may be possible to get, but not set, the HW
timestamping configuration on some specific interfaces like macvlan in
containers. This would require the admin to configure the timestamping
before starting chronyd.

If SIOCSHWTSTAMP failed on an interface, try SIOCGHWTSTAMP to check if
the current configuration matches the expected configuration and allow
the interface to be used for HW timestamping.
