QFileInfoGatherer: remove m_resolveSymlinks for non-Q_OS_WIN

For some reason, m_resolveSymlinks was never set to true for
non-Windows systems. The constructor set it to false and the
setter was only implemented for Windows.

So remove the member and code that is only executed if it
is set to true, except on Windows.
