Bug#1080198: h5py: autopkgtest regressions with mpich as default provider on 32 bit architectures

Followup-For: Bug #1080198

As far as I can read the test log, the mpich (32-bit) tests are not
actually failing.  It looks like the error conditions is occuring
afterwards during shutdown.  Perhaps some test files need to be
explicitly closed before shutdown.
