Sasha Levitskiy 3c97fa78cd build: tools: Add json collection of installed files with hashes.
Adds installed-files.json in addition to installed-files.txt
Further sorts the file list to be ordered within the same size bucket.

Test: manual, cross-checked checksums with sha256sum utility
      checked build outputs.
