Always check tools for build at the same place

Let's only check non-build verb tools early and check build verb
tools at the same place regardless of whether the verb is build or
not to keep things more consistent.

As a side effect this allows building tools from source to do the
build in sync scripts which is done in
https://github.com/davide125/arcadeos/blob/main/mkosi.sync.
