net-misc/iputils: fix build with USE="-caps"

Upstream patch. Without this change, attempting to emerge
net-misc/iputils-20190515 with USE="-caps" without having
had sys-libs/libcap installed for some other reason will fail during
src_configure due to wrong type of arguments for add_install_script.
