Revert "qdoc: Query environment variables from qmake"

this change is misguided:
- for the qt doc build, the correct way is to adjust qt_docs.prf to feed
  the right data
- projects which are actually outside qt have no business in using these
  variables (and the data they refer to)

This reverts commit 61062f6769670b1a33c3f4406d51892c221a26fd.
