Release version 1.0.4

Fix APK signing:
- Implement control checksum calculation for APKINDEX
- Correctly sign APKINDEX given an RSA certificate

Fix: APK generator now uses actual package architectures

Alpine packages use x86_64 while the default --arch flag is amd64.
The generator was only iterating over config.Arches, causing a mismatch
that resulted in empty repositories. Now iterates over architectures
found in the packages themselves, matching RPM generator behavior.
