[Bug report] barcode-scanning doesn't ship riscv64 binary

[tadfisher]

Describe the bug
AGP updated the default ABI filters to include riscv64, which causes apps using barcode-scanning without setting ABI filters to fail when uploading to the Play Store. This is because libbarhopper_v3.so is not available for the riscv64 ABI within the AAR.

Expected behavior
barcode-scanning should probably build libbarhopper_v3.so for riscv64, or the ABI restriction should be documented.
