selftests/landlock: Build without static libraries

Browse source 
commit 091873e47e upstream.

The only (forced) static test binary doesn't depend on libcap.  Because
using -lcap on systems that don't have such static library would fail
(e.g. on Arch Linux), let's be more specific and require only dynamic
libcap linking.
