Isolate Python dependency tree from native build system

Summary:
**Context:**
Thrift Python builds require different library versions and configurations than native C++ builds. `fbthrift-python` does not require `proxygen`, yet `proxygen` is included as a dependency, which makes the build unnecessarily brittle. Current manifests mix Python and C++ dependencies.

**This diff:**
- New `libaio-python` manifest for Linux-only Python builds
- `-python` manifests (`fbthrift-python`, `folly-python`, `fizz-python`, `zlib-python`, `libiberty-python`) now depend on `-python` variants instead of base manifests
- Fix `zlib-python` download URL (github instead of `zlib.net`)
- Exclude `http2_helper` test extension from `fbthrift-python` build (removes `proxygen` dependency)
- **Bonus** - Add build status badges for the python builds.
