QmakeProjectManager: Fix Makefile compatibility checkv13.0.0-beta2

E.g. qmake "binaries" for Android are actually shell scripts that call a
Desktop qmake in a different location, which lead Qt Creator to conclude
that the directory contains an incompatible build.
Fix this by checking that the -qtconf argument passed to qmake points
into the real qmake's parent directory, as is the case in the
abovementioned scenario.

Fixes: QTCREATORBUG-30354
