iproute2: revert add libcap support, enabled in ip-full

This reverts commit a6da3f9ef7.

The libcap isn't as optional as the commit messages suggests. A hard
dependency to the libcap package is added, which is only available in
the external packages feed. Therefore it is impossible to package
ip-full without having the external packages feed up and running, which
is a regression to the former behaviour.
