Bump netlayer to use tor binaries from verified tor-browser v9.5.4

[cd2357]

Use a netlayer version that includes tor binaries extracted from the latest tor browser v9.5.4.

For simplicity:

• use netlayer version cdbe476 (based on commit cdbe476 from this branch)
  • the referenced branch = previously used netlayer v0.6.8 + a change to use following tor-binary
• above netlayer bumps tor-binary dependency to f3bc31f (based on commit f3bc31f from this branch)
  • the referenced branch = previously used tor-binary dependency + change A + change B
    • change A: extract tor binaries from tor-browser v9.5.4 (instead of 9.5.3 used previously)
    • change B: update the extraction and build process to check if the SHA-256 hashes of the tor-browser binaries match the official ones (instead of SHA-512 hashes used previously, which are not published in the official tor repo anymore)
      • this ensures the build only succeeds if the downloaded tor-browser binaries (used to extract the tor binaries) match the official checksums

Note: The tor binaries in tor-browser v9.5.4 are the same version as from v9.5.3 (namely tor v0.4.3.6, as per the tor-browser changelog).

So this PR doesn't bring or change any tor or netlayer functionality. It only ensures that the used tor binaries were extracted from verified tor-browser packages. The tor binaries are delivered as dependencies of netlayer.

Fixes #4593
