To minimize external library dependencies for Swift unit
tests and SAIO, PyECLib 1.1.1 introduces a native backend
'liberasurecode_rs_vand.' This patch is to migrate over
the unit tests to the new ec_type when available.
This change will work with current pyeclib requirements
(==1.0.7) and also future requirements (>=1.0.7).
When we're able to raise *our* requirements to >=1.1.1 we
should remove jerasure from the list of preferred backends.
Related SAIO doc and example config changes should be
included with that patch.
