Yousong Zhou e8f79474c9 libpcap: build with cmake
The main motivation is to drop and stop maintaining
"100-debian_shared_lib.patch".  It lacks the logic to include custom
implementation of several functions like pcap_strlcpy() which can cause
build failures when glibc is used [2]

CAN and CAN-USB support related symbols are now handled by general linux
support, see [1]

"-ffunction-sections -fdata-sections" were removed as they should help
much for shared libraries
