Fix two null pointer crashes of breakloop and can_set_rfmon

pcap_open_dead and pcap_fopen_offline has not initialized the breakloop_op and can_set_rfmon_op callback respectively,
if pcap_breakloop() is called followed by pcap_open_dead() and pcap_can_set_rfmon() is called followed by pcap_fopen_offline()
then the null function pointer crashes will happen.

This commit adds two default implementation pcap_breakloop_dead and sf_cant_set_rfmon and uses them to initialize those two missed callbacks.
