feat: enhance package dependency handling and signing process

- Updated `lib32_dependencies` method to ensure the package name is included in runtime dependencies if not already present.
- Modified the signing key loading process to allow for multiple password attempts, improving user experience during key access.
- Introduced functions for staging licenses of split packages, ensuring proper symlink creation for matching licenses and copying distinct ones.
- Added tests for verifying the correct functionality of manpage compression and license staging.
