[meta-qt5][PATCH] qtbase: replace host paths with qmake built-in properties in qconfig.pri

[Jonathan Liu <net147@gmail.com>]

This avoids qconfig.pri in the Qt SDK incorrectly including paths from
the build host that may not exist on the SDK host. As the paths are
now correct, qmake can correctly detect system include paths and use
-isystem instead of -I for Qt's include directories which allows the
suppression of warnings from library headers when building Qt
applications.
