stake-pool: Downgrade dependencies for fixed release

#### Problem

The current spl-stake-pool crate doesn't always work due to its
dependency on spl-math which still uses the v1 Solana crates.

#### Summary of changes

Since the spl-math dependency wasn't actually needed, it was removed in
solana-labs#7421. So just to get a new patch release out, downgrade the local
dependencies.

This will fail CI, but after it lands we can tag the release, and revert
this PR.
