link type 101 should be converted to 12 to avoid pcap_compile_nopcap error

[crackevil]

Brief description

link type 101 is described as raw as the same of link type 12, but it will fail function pcap_compile_nopcap(), or some others referring link type. this issue was found at tcpdump() function in utils.py. it uses PcapReader's link type as it, but link type 101 is NOT defined in dlt.h of libpcap. it should convert to 12( not very sure) which is also defined as raw ip.
