QFSFileEngine: update d->fileEntry after a successful rename

Otherwise member methods such as size() could return incorrect info.

Add setFileEntry(QFileSystemEntry &&); to reuse a QFileSystemEntry if we
have already constructed one.

As a result of this, a QTemporaryFileEngine::setFileName() call has
become redundant and can be removed; the code it executed is already
taken care of:
- QFSFileEngine::close(): already called by QTFEngine::rename() a couple
  of lines above
- QFSFileEngine::setFileName(): QTFEngine::rename() calls
  QFSFileEngine::rename() which in turn updates the `fileEntry`

This commit is covered by tst_QTemporaryFile::rename(), i.e. if
QFSFileEngine::rename() didn't update the fileEntry, that test would
fail.
