Description: disable blosc on arm
 blosc compression is not functional due to the reliance on unaligned
 memory access. This patch replaces all blosc write functionality with
 zlib (default fallback) and disables a test reading blosc compressed data.
 One could also disable reading by removing it from all_complibs in
 tables/filters.py but that would require fixing up all tests to expect
 exceptions.
