vlan: partially enable SIOCSHWTSTAMP in container
[ Upstream commit 731b73dba359e3ff00517c13aa0daa82b34ff466 ]
Setting timestamp filter was explicitly disabled on vlan devices in
containers because it might affect other processes on the host. But it's
absolutely legit in case when real device is in the same namespace.
