vendor: update github.com/opencontainers/runc to main

it is not possible yet to drop the override since the latest released
version has an indirect dependency on github.com/cilium/ebpf that
causes the binary to grow by ~1MB.  Once there is a new runc version,
we can drop the override.

For now just bump to the latest version on main, since we are using a
year old version at this point.
