torcx removal: address PR comments

- updated github actions for runc, containerd, and docker to not handle
  nonexistent ebuilds in app-torcx/ anymore
- removed spurious package_run_dependencies from build_image_util.sh
- build_sysext: generate pkginfo before mangle script runs
  use zstd for compression; add cli flag to select compression
- ci_automation_common.sh: remove spurious `/` from match string
- coreos, board-packages, bootengine: bump ebuild revisions
- kernel commonconfig: add squashfs zstd support
