fix(pdm): add rsyslog and convert pdm-test to setup_deb822_repo

- Install rsyslog to fix '/dev/log: Connection refused' errors
  (Debian 13 minimal containers don't have rsyslog by default)
- Convert pdm-test heredoc to use setup_deb822_repo with enabled=false

Requires: fix/setup-deb822-enabled-param branch for enabled parameter
