libs/utils/env: add required tools dependencies

Once the user defined a tool in the configuration file that tool
can have dependencies on other tools. Currently we require the
user to know and list all that dependencies.

This patch simplify things by automatically adding all the known
dependencies of each user tool the user can specify.
