Apps created by qt_internal_add_app are placed in a bin/Release subfolder in a -debug-and-release build

With a -debug-and-release Qt build, apps created by qt_internal_add_app (but not tools created by qt_internal_add_tool) are placed in config specific directories.

$ ls ../qtbase/bin/Release
androiddeployqt   androidtestrunner qmleasing

This is with a non-prefix build. Need to check if at least the installed files are in the proper location.

These should be placed under bin directly.
