Subject: Remove case consistency check at startup. (#7585)

- This was needed when we transitioned to all lowercase packages because
  git didn't handle case changes well on case-insensitive filesystems.

- Now it just adds extra stat calls to startup, and we check for
  all-lowercase package names in tests, so we'll remove it.

- people using really old versions of Spack can re-clone.
