[WIP] thunderbird: pass less non-standard flags

[lukateras]

Prerequisite to #36449. Not tested yet.

This would not build for me. I've pushed two new commits on top of it that get it building and basically working:

https://github.com/jerith666/nixpkgs/tree/thunderbird-config-flags
c56165f Merge remote-tracking branch 'channels/nixos-unstable' into thunderbird-config-flags
c68c301 thunderbird: add libpulseaudio build input, disable tests

Only issue I've noticed is that pushing the "play" button in the preferences dialog to test the new-mail sound doesn't work. But I'm not sure it did before those changes either.

Oh, also: the test failure looks like this:
