container-entrypoint: Switch to POSIX shell

richardweinberger · jan-kiszka · commit 6df962506ae2 · 2023-04-20T22:01:31.000+02:00
kas-container is carefully written to be POSIX shell compliant.
Let's do the same with container-entrypoint to be consistent.
While we're here, remove the only bashism used in container-entrypoint.
