fluffychat: 1.2.0 -> 1.2.10, build from binary

I understand that this may be a controversial change.
Here is my reasoning:
 - Fluffychat in nixpkgs has been broken since August
   because of reproducibility issues
 - Flutter in general has very bad nondeterminism going on with hashes,
   see https://github.com/NixOS/nixpkgs/issues/211606
 - End users are most likely to care about the programs working. It wasn't working earlier.
   Source builds at least won't break randomly.
