Subject: [PATCH] fix(oci): say where the converter entry point has to run

Fetched with wget and piped to bash, $0 is "bash" and the script resolves
its own directory to wherever the shell happens to be. It then reports
"shasum: /root/requirements.txt: No such file or directory", which names
a path the reader never chose and says nothing about the real problem.

It now checks for the files it needs and names both places it runs from:
the installed engine directory on a Proxmox host, or oci/ in a clone.

PACKAGE-CONTENTS.md called it the "installer entry point", which is what
invites fetching it over the network in the first place.
