debian/tests: fix architecture-specific test failures

Pass the previously computed $DESELECT option to pytest; it was set for
ppc64el but never actually appended to the pytest command line, so the
Welch spectrum skip never took effect there.

Also handle 32-bit architectures explicitly:

- ppc64el: deselect test_spectrum_complex[welch-False]. A Welch PSD bin
  can underflow to exactly 0.0 (denormal/flush-to-zero behavior), which
  triggers a "Zero value in spectrum" UserWarning that MNE/pytest turn
  into a FAIL (filterwarnings="error:").

- armhf/i386: skip via -k the non-parameterized test_peak_finder and
  test_split_saving_and_loading_back. C long is 32-bit here, so
  np.index/int indices come back as int32 (peak finder asserts int64),
  and MNE's split-file size prediction misses the last expected file.

- armhf/i386: deselect test_decimate_surface_vtk[2..4]. Debian VTK on
  32-bit builds vtkIdType as int32, but MNE casts triangle indices to
  np.int64 before numpy_to_vtkIdTypeArray, raising ValueError. The [0]
  and [1] variants do not exercise the VTK path and stay enabled.

Architectures not affected (amd64/arm64/s390x) keep running the full
suite: both KEXTRA and DESELECT expand to nothing for them.
