Don't set paths and versions of build dependencies

See merge request !6

This lets tools/win32/configure.ps1 from the icinga2 repo control the build
dependency paths and thereby the dependency versions. So different branches of
the icinga2 repo can use one branch of the windows-icinga2 repo to build
against different dependency versions. This is currently required by our GitHub
Actions as all branches there use the master branch of this repo.
