Use canonical path for CNB builder lifecycle binaries

This commit changes the path used to invoke lifecycle binaries in
CNB builders from `/lifecycle` to `/cnb/lifecycle` to conform to
the CNB spec. This will ensure the build plugin image-building
goals and tasks are compatible with future versions of builders
that may not support both paths.

See gh-23009
