libpcap: fix build failure related to libnl3
When libpcap detects that libnl3 is available, it hardcodes the fact
of using -I/usr/include/libnl3, which is completely wrong in
cross-compilation.
This commit fixes that, by removing this hardcoded include path, and
by passing an appropriate -I option from libpcap.mk.
The original issue has been reported upstream at
https://github.com/the-tcpdump-group/libpcap/issues/305.
Fixes:
