salt's pip.installed flagged so_pillar_psycopg2_in_salt_python as
failed because pip exits non-zero when it can't find the patchelf
binary to rewrite the psycopg2 wheel's RPATH after extraction. The
wheel is fully installed and importable regardless — the patchelf
step is a cosmetic post-install rewrite, not a build dependency. But
salt's failure cascade then short-circuited so_pillar_initial_import
and the so-yaml mode flip, leaving the install in dual-pillar mode
instead of PG-canonical.
Replaced with cmd.run that runs pip with `|| true` and uses an
`import psycopg2` check as the actual readiness gate — same idea as
how salt's own bootstrap does it. Also fixed the require: ref on
so_pillar_initial_import (was `pip:`, needs to be `cmd:` for the new
state type).
