pgadmin: make the container entrypoint executable (image smoke)

COPY preserves the non-executable mode 644 from the OBS payload source
file, causing crun to refuse execution of the entrypoint. Add explicit
chmod 0755 RUN layer after COPY to make the file executable in the
image, and chmod +x the source file to track the correct mode in git
(belt and braces).

 # Overridable defaults: docker/podman -e wins over ENV, and the RPM's
