Fixed: QFileInfo::lastModified() returning wrong value.

Fixed so that empty QDateTime is returned for non existing file.
Fixed also created() and lastRead() to return empty QDateTime for
non existing file.

QFileSystemEngine::fillMetaData() returned true for non existing
files. This was also corrected.

Task-number: QTBUG-25811
