Give the puppetserver compilers the Vault cert helpers (#482)

profiles::pki::vault and profiles::ssh::sign shell out to
/usr/local/bin/certmanager and /usr/local/bin/sshsignhost from generate()
during catalog compilation. Neither binary exists in the compiler image, so
every node using them fails to compile.

- install certmanager v0.2.0 and sshsignhost v0.1.0 onto the shared bin volume with sha256 verification
- wrap both at /usr/local/bin from a pre-default entrypoint hook, failing startup loudly if either is missing
- mount read-only Vault configs for both: kubernetes auth on k8s/au/syd1, internal CA verified rather than skipped
