TST, MAINT: expand OpenBLAS version checking

* add a function to tools/openblas_support.py
that may be used to test OpenBLAS version
available through NumPy in a manner agnostic
to any specific CI service

* expand OpenBLAS version checking to include
ppc64le and POWER8 CI runs; a separate PR will
be provided to bump these versions to 0.3.7.dev

* OpenBLAS install was broken on ppc64le
Travis CI after migration to tools/openblas_support.py;
fixed that

* Azure CI config no longer uses a single-line
280-character Python "program" assigned to an
environment variable to check OpenBLAS version;
instead, it now leverages tools/openblas_support.py
to perform the same operation using a conventional
Python function
