increase nixpkgs-review timeout to 120 minutes, increase python max package rebuilds from 25 to 100

Recently we've been running nixpkgs-update on better hardware and have also increased the number of workers so I think it makes sense to increase this timeout.

Increasing the python rebuilds was discussed in #185.

I'll wait a week for comments before deploying this to build02. nix-community/infra#1169

The original thought process was that packages which have more than 25 rebuilds are much more likely to have downstream failures, thus better suited for the batch updates we do periodically.

That being said, I would be fine with bumping this to 50 or 100. But 500 is almost 10% of the python package set. Too much.

bumping this to 50 or 100

#185 (comment)
100 or 250 would be a cool upgrade

@mweinelt Are you still okay with 100?

Thanks for following up on this @zowoq
