test: Add a workaround for lacking Podman networking

jajik · jajik · commit c4424a44f66e · 2025-11-13T10:15:03.000+01:00
Unfortunately, custom podman networks do not support rDNS so tomcat
requests are handled by their IP. This causes our `Require host` to
not work which leads to test failures.

Upon httpd container start, we try to detect podman and if needed,
we change `Require host` to `Require ip`.
