remove the cap PKGCONFIG its redundant and everything in recipe wants
it enabled, it was  added just for having consistent builds otherwise
it was autodetected by autotools and if you had libpcap staged then it
was enabled automatically otherwisie not.

so you can either change PACKAGECONFIG ??= "" to PACKAGECONFIG_append = " cap"

or remove this completely and add the dependencies on libcap unconditionally.
