make sure that Python dependency is actually used for VTK 9.0.1

(created using eb --new-pr)

edit (by @boegel): this fixes the following compilation error:

error: lvalue required as increment operand 154210 | ++Py_REFCNT(o);

Culprit is system Python 3.10 being used, see also https://gitlab.kitware.com/paraview/paraview/-/issues/21511 and EESSI/software-layer#204

I tried

configopts += "-DPython3_ROOT_DIR=$EBROOTPYTHON "

which appears in later easyconfigs for VTK, but that didn't work:

I guess we should also try and check whether the -DPython3_ROOT_DIR is really correct, also when a newer system Python version is available too
