io: Update Dockerfile

Build Io interpreter and packages from source in latest Ubuntu.

The interpreter looks for packages under `eerie` in the current
directory, so create the symlink in the Makefile that is "building" each
step.

Now the Regex package no longer prints a message when loaded, so no need
for the special treatment in `run`.
