Dockerfile: update runc binary to v1.2.3

This is the third patch release of the 1.2.z release branch of runc. It
primarily fixes some minor regressions introduced in 1.2.0.

- Fixed a regression in use of securejoin.MkdirAll, where multiple
  runc processes racing to create the same mountpoint in a shared rootfs
  would result in spurious EEXIST errors. In particular, this regression
  caused issues with BuildKit.
- Fixed a regression in eBPF support for pre-5.6 kernels after upgrading
  Cilium's eBPF library version to 0.16 in runc.
