[Buildroot] [git commit branch/2018.02.x] wireshark: fix static build

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=0af2651146bf87ba5476eaaa8df39d1b40c73469
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

Don't give a path in --with-pcap option otherwise PCAP_CONFIG won't be
used (see AC_WIRESHARK_PCAP_CHECK in acinclude.m4) to retrieve pcap
static dependencies such as -lnl-3 and as a result pcap detection will
fail
