Testsuite: use XLSX for Octave and MATLAB ≥ R2012a, and XLS for MATLAB < R2012a

In 98bdf76581, all XLSX files were removed in
favour of XLS, for compatibility with MATLAB R2009b.

But this broke the very same tests under Octave, since XLS support is not very
good there.

This commit implements a solution that works everywhere, by using XLSX whenever
possible, and XLS otherwise.
