Refine ScanCode.io pipeline for ELFs

Update pipelines steps for the binary to source analysis for native ELF using strings and symbols, and not only DWARFs

From #1339:

There seem to be too many "requires-review" as a first glance in the summary report from a d2d project for ELF.

• https://github.com/aboutcode-org/back2source-data/blob/main/data/archive.fedoraproject.org/pub/fedora/linux/releases/40/Everything/x86_64/debug/tree/a/atomix-debugsource-44.0-4.fc40.x86_64/d2d-summary.json#L36 has only one requires review

• https://github.com/aboutcode-org/back2source-data/blob/main/data/archive.fedoraproject.org/pub/fedora/linux/releases/40/Everything/x86_64/debug/tree/a/atomix-debugsource-44.0-4.fc40.x86_64/d2d-details.json#L3535 has many correctly mapped paths that are marked as requires-review likely incorrectly

• Also we should not include directories and <artificial> and <built-in> (and this may something we could filter out in the elf-inspector ?)

  • like in https://github.com/aboutcode-org/back2source-data/blob/main/data/archive.fedoraproject.org/pub/fedora/linux/releases/40/Everything/x86_64/debug/tree/a/atomix-debugsource-44.0-4.fc40.x86_64/d2d-details.json#L3398
