gnu: Respect --cores build argument in some python packages.

Reported by Greg Hogan <code@greghogan.com> in #74445.

* gnu/packages/astronomy.scm (python-asdf-astropy, python-astropy,
python-photutils, python-poppy, python-regions, python-reproject,
python-sunpy, python-spectral-cube, python-stdatamodels, python-pysiaf,
python-sbpy, python-asdf-coordinates-schemas, python-roman-datamodels,
python-webbpsf, python-yt):
[arguments]<test-flags>: Adjust "-n" or "--numprocess" to respect
"--cores" build argument.

* gnu/packages/check.scm (python-crosshair): Likewise.

* gnu/packages/databases.scm (python-fastparquet, python-pycurl, awscli,
python-s3transfer): Likewise.

* gnu/packages/python-xyz.scm (python-glymur, python-zarr, python-dask):
Likewise.
