package/kismet: add optional support for libcap
When libcap was compiled before, kismet will use it as optional
dependency:
$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/kismet_server | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [libcap.so.2]
[...]
The build system offers no option to en-/disable libcap support:
