Commit "170777f342 package/qt5/qt5virtualkeyboard: convert to qmake
infrastructure" changed most but not all <pkg>_QMAKEFLAGS to
<pkg>_CONF_OPTS.
As a consequence, BR2_PACKAGE_QT5VIRTUALKEYBOARD_LANGUAGE_LAYOUTS is
ignored and all layouts are compiled in.
Some layouts have different licenses (e.g. pinying), so the license
information for a build that is configured to not include such layouts
is wrong.
Change the remaining _QMAKEFLAGS entry, fixing the config for which
language layouts are compiled and installed.
