py-scipy: update to 1.5.2

Done to fix build w/ gfortran 10. "make test" was mostly OK except for
three tests that returned nan where inf was expected ...

Highlights of this release:
  wrappers for more than a dozen new LAPACK routines are now available
  in scipy.linalg.lapack
  Improved support for leveraging 64-bit integer size from linear algebra
  backends
  addition of the probability distribution for two-sided one-sample
  Kolmogorov-Smirnov tests

New features:
  Too many; see release notes at github.

Backwards incompatible changes:
  The output signatures of ?syevr, ?heevr have been changed from
  w, v, info to w, v, m, isuppz, info
  The order of output arguments w, v of <sy/he>{gv, gvd, gvx} is
  swapped.
  The output length of scipy.signal.upfirdn has been corrected, resulting
  outputs may now be shorter for some combinations of up/down ratios and
  input signal and filter lengths.
  scipy.signal.resample now supports a domain keyword argument for
  specification of time or frequency domain input.
