[Philipp Rüssmann]

We relax this test because sometimes for no apparent reason the qdos test fails on the test machine. While neither valgrind nor totalview with both ifort and gfortran can find any reason for corrupt memory this seems to happen sometimes leading to slightly wrong values in qdos.01.1.dat. Thus the test is relaxed to require more than one file to differ.
