chore(3p/nixpkgs): Bump nixpkgs channels to 2021-08-04 r/2710

I used //tools/depot-nixpkgs-update for this - thanks again, sterni!

Included fixes:

* temporary workaround for building notmuch python package, fixed in
  upstream already (but channel hasn't advanced there)
* Disable fprintd in grfn.system.yeren, as the fprintd-tod package
  currently has a version mismatch in nixpkgs
