[Buildroot] [PATCH v2 1/1] package/python-scipy: bump version to 1.9.1

[Guillaume W. Bres]

scipy.tar.xz is no longer released.

A new "python.h" missing header build time failure arised,
it is fixed with a new -I cflag.

New runtime/linking errors appeared on architectures that need
libatomic, an -latomic linker flag solves them

Scipy is expected to move to a meson build infrastructure
by the next release
Once 1.9.2 is out, we know we already have my V3-1.9.1 patch
serie that builds "fine" with meson, it involved a minor tweak
(hopefuly solved by this time). The test script no longer did pass though,
this serie is not 100% ready to go

Thanks Guillaume for the patch, and sorry for the very long delay. In
the mean time, James has posted a more recent update, which uses the
meson infrastructure, so we've applied that as commit
42127f01bc08211e1dbba2cac7425488dee7dc3a.

Best regards,

Thomas
