Improved arm64 support

[GavinPacini]

The arm64 port of Tor Browser often does not have the same versions available as the official upstream. So, we need to track two hardcoded versions, one for amd64 and one for arm64.

Further to this, fetching the latest remote version does not work for arm64 so we also just fallback to the hardcoded version in this case.

tb_remote_version_parser runs after tb_update_check. This would then output a false console output:

echo "INFO: Find out latest version... Downloading...: $TBB_VERSIONS_FILE_LINK"

But even with that resolved would be kinda stub, hacky implementation... For a full implementation...

Do you think you could parse https://sourceforge.net/projects/tor-browser-ports/files/ instead, add that to the version parser or create an alternative version parser?

Version parser doesn't necessarily need to be written in bash. Could be any language which you might (I dunno) be more comfortable with, seem more suitable. Download could be done by update-torbrowser. Parsing could be done by an externally called script written in a memory safe language to be discussed such as python. (With dependencies available from packages.debian.org.)

Here is a parser but needs some more work integrating it.
