fix: lake: Lean shared lib path before the workspace's (#7796)
This PR moves Lean's shared library path before the workspace's in
Lake's augmented environment (e.g., `lake env`).

Lean's comes first because Lean needs to load its own shared libraries
from this path. Giving the workspace greater precedence can break this
(e.g., when bootstrapping), This change does not effect shared library
path on Windows (i.e., `PATH`) because such shared libraries are already
prioritized by being located next to the executable.
