py-numpy: updated the BLAS patch for more likely upstream inclusion

This introduces a 'generic' variant for blas_opt_info() and
lapack_opt_info() that looks into BLAS_LIBS and LAPACK_LIBS. The
others stay alive, and you can choose via NPY_BLAS_ORDER and
NPY_LAPACK_ORDER.

Will post this upstream … hoping for the best.

Other projects seem just to abuse the [openblas] entry in
site.cfg, or whatever hacks to trick this into building with
a generic BLAS. One hurdle is that using openblas seems to
assume that CBLAS is present in there, which it is not in pkgsrc.

We could think about introducing some alternatives stuff that uses
stubs for all the related libs anyway, but that is not my application,
which builds things from source. For binary packages, it would be
interesting, though. See Debian and Genoot for prior art on that.
