Switch the basic conditionals based on the bootstrap's value

We always switch rpmswheels, optimizations and tests when bootstrapping
new Python version, so they can be tied to the bootstrap conditional.
With that, switching the bootstrap in Koji side tag will be possible,
letting us to avoid separate "bootstrap" and "rebuild" commits.
