[Buildroot] [git commit] reaver: fix static link build issue

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=559416ffe2039d1cac94e348bd28e963adf008a4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libpcap itself is linked against other libraries, reaver fails to
build as it doesn't link with libpcap dependencies. This patch fixes
that by using the pcap-config program.

Fixes:
