sdk: fix host_build QT_ARCH

mkpecs/qconfig.pri defines QT_ARCH and QT_BUILDARCH separately
for host_build and target build and both of these were always
set to target architecture. This cause issues in the SDK, if
component tried to build host tools using these values, which
qtwebengine does.

Fixed now, so that the host_build variants are taken from the
nativesdk's mkspecs/qconfig.pri.
