When cross compiling on amd64-linux by CGO_ENABLED=1 GOOS=linux GOARCH=mips CC=mips-linux-gnu-gcc CGO_LDFLAGS="-L/tmp/libpcap-$PCAPV" go build, this error would occur:

# github.com/gopacket/gopacket/pcap
../../../go/pkg/mod/github.com/gopacket/gopacket@v1.3.0/pcap/pcap_unix.go:355:18: cannot use _Ctype_gopacket_time_secs_t(ci.Timestamp.Unix()) (value of type _Ctype_gopacket_time_secs_t) as _Ctype___time64_t value in assignment
../../../go/pkg/mod/github.com/gopacket/gopacket@v1.3.0/pcap/pcap_unix.go:356:19: cannot use _Ctype_gopacket_time_usecs_t(ci.Timestamp.Nanosecond() / 1000) (value of type _Ctype_gopacket_time_usecs_t) as _Ctype___suseconds64_t value in assignment

After some investigation, the reason is that the C macro at the beginning of pcap/pcap_unix.go failed to define gopacket_time_secs_t and gopacket_time_usecs_t properly.

This commit fix it and it works well when cross compiling with per-compiled libpcap.
