CI: invoke Chez via a scheme wrapper, not a symlink

Browse source 
Chez derives its boot-file name from argv0, so a symlink named chez looks for a
nonexistent chez.boot (CI failed at the first gate step). Replace the symlink
with a wrapper that exec's scheme, preserving argv0 so the boot files resolve.
