Unfree packages aren't distributed by our binary cache due to legal
reasons[1] and are usually a prebuilt binary that requires some patching.
When using distributed builds[2], those are uploaded to another build
machine as fixed-output derivations from `fetchurl` are built locally[3]
which takes a certain amount of time and resources with almost no gain
as the build process is trivial in contrast to the up/download to a
remote builder.
This is why I figured that at least some of the packages should be
explicitly built locally, I've done something simlar for
`citrix_workspace` already in the past[4].
The following packages are affected by this:
* `idea.*` (excluding free derivatives)
* `xmind`
* `teamviewer`

Triggering this setupHook for dependencies at targetOffset does not work
in cross-compilation cases where such a dependency is lacking. This
simplified setupHook is more robust.
