--skip-package-regex and --skip-package-regex do not work in rev mode

[Atemu]

Trying to review a huge staging PR, I used --skip-package-regex to skip over a few packages that I know wouldn't be broken or that I don't want to build this worked in pr mode. Cloning the PR and trying to run nixpkgs-review rev HEAD -b ... --skip-package-regex ... does not actually skip package names that match the regex which is extremely confusing.

nixpkgs-review should either support --skip-package in rev mode or error out, rather than silently ignoring the flag.

An easy way to repro this is to create a commit touching hello in some way (i.e. breaking it) and then running with --skip-package hello. It should not build anything but in actuality it tries to build hello.
