python: Fix CVE-2021-3177

A buffer overflow can occur when calling c_double.from_param().

Advance to python-2.7.5-92.el7_9.src.rpm.  Fixes CVE-2019-20907,
CVE-2020-26116, and CVE-2022-0391 as well.

=== Testing
Build and boot iso; log in.

$ python
>>> from ctypes import c_double
>>> c_double.from_param(1e300)

The last line will cause python to abort if the fix
has not been applied.

Ran ansible to provision system.  Unlocked.  Rebooted to unlocked
and enabled host-list status.
