Fixed #28401 -- Allowed hashlib.md5() calls to work with FIPS kernels.

Browse Source 
md5 is not an approved algorithm in FIPS mode, and trying to instantiate
a hashlib.md5() will fail when the system is running in FIPS mode.

md5 is allowed when in a non-security context. There is a plan to add a
keyword parameter (usedforsecurity) to hashlib.md5() to annotate whether
or not the instance is being used in a security context.

In the case where it is not, the instantiation of md5 will be allowed.
See https://bugs.python.org/issue9216 for more details.

Some downstream python versions already support this parameter. To
support these versions, a new encapsulation of md5() has been added.
This encapsulation will pass through the usedforsecurity parameter in
the case where the parameter is supported, and strip it if it is not.
