Fix tst_qfileinfo crash on windows with UAC enabled

Creating symbolic links requires admin privilege by default - when UAC
is enabled then even users in the administrators group do not have admin
privileges without an escalation prompt. (which is inappropriate for an
autotest).

When run with insufficient privileges, the test is skipped with a warning
