[OE-core] [PATCH 2/3] qmake_base.bbclass: add generate_qt_config_file task

[Otavio Salvador]

This writes a qt.conf inside WORKDIR to properly configure projects
based on CMake. This is required since qmake variables (returned
by -query command) are fixed into the binary and can only be
changed using a qt.conf file.
