Use nixosTest.quickBuild behavior by default

Browse source 
This wasn't the default behaviour because:

> We don't enable this by default to avoid the mostly unnecessary work of
> performing an additional build of the package in cases where we build
> the package normally anyway, such as in our pre-merge CI.

Since we have a componentized build, we've solved the duplication.

In the new situation, building both with and without unit tests
isn't any slow than just a build with unit tests, so there's no
point in using the unit-tested build anymore.

By using the otherwise untested build, we reduce the minimum build
time towards the NixOS test, at no cost.

If you want to run all tests, build all attributes.
