[oe] [meta-qt5][PATCH 2/2] qtbase_git: install qt.conf for the target

[Jeroen Hofstee]

The build-in qmake settings point to the sysroots on the host machine.
Running qmake on the target hence errors with:

  Could not find qmake configuration file linux-oe-g++.
  Error processing project file

So add qt.conf to the target image with the correct locations.
