Add sqlite to Windows Phone default build

sqlite 3.8.5 supports Windows Phone 8.1. Make required
adaptations and add it to the default build.

For WinRT and Windows Phone the QSqlQueryModel unit-test
fails, both with plugin compiled and using the system
sqlite. Root cause seems to be deep inside sqlite, hoping
for a fix soon. However, all other tests pass and hence we
should enable it.
