face: handle PcapHelper::Error when applying multicast configuration

When the network interface state is changed, NFD reconfigures its
multicast ethernet faces. The code responsible for this is prone to
a TOCTOU race condition, e.g., if an interface is quickly brought up
and then down again. This currently raises an uncaught exception when
we try to set a packet filter for that interface.

Prevent this issue by catching PcapHelper errors in the same manner
as we catch EthernetTransport errors, and skip creating the face.
