Issue:
Changing configure flags for `pie build` does not result in a full rebuild
Working with #83:

I'm not sure if my Makefile / configure script is incorrectly written and does not properly handle the build dependencies, but given the fact that `pie` always runs both `phpize` and `./configure` for each build, it would probably make sense to run the equivalent of `git clean -fdx` in the build directory to ensure that the build is internally consistent. Even if the build infrastructure is actually faulty, this could otherwise lead to hard-to-debug issues.

Pull request:
(feat) : Enhance UnixBuild with proper cleanup and improved test organization
Fixes #93 

This PR enhances the UnixBuild class and its tests with the following improvements:

### Changes
- Added cleanup functionality to UnixBuild to remove build artifacts
- Refactored UnixBuildTest for better organization and maintainability
- Added explicit tests for cleanup behavior
- Improved error handling and verbose output

### Technical Details
- Added `cleanup()` method to handle `make clean` and `phpize --clean`
- Reorganized tests with proper setup and helper methods
- Added test cases for verbose output and cleanup scenarios
- Improved error handling with proper cleanup in failure cases
