managed-token: Remove ignored profile.release (#3728)

The SPL build currently gives this warning every time:

```
warning: profiles for the non root package will be ignored, specify profiles at the workspace root:
package:   /home/jon/src/solana/solana-program-library/managed-token/program/Cargo.toml
workspace: /home/jon/src/solana/solana-program-library/Cargo.toml
```

Remove the ignored `profile.release` configuration in managed-token.
