script/setup/install-runc: build runc statically

The test tarball from test/build.sh is built on the kubekins image and
run on other distros. A dynamic runc built on Debian trixie needs
GLIBC_2.38 and fails on AL2023 (kubernetes/kubernetes#142987).

Build with `make static` like the runc release binaries. EL has no
libseccomp-static, so the Fedora/EL VMs keep the dynamic build via
RUNC_DYNAMIC=1.
