gh-95231: Disable md5 & crypt modules if FIPS is enabled (GH-94742) 
If kernel fips is enabled, we get permission error upon doing
`import crypt`. So, if kernel fips is enabled, disable the
unallowed hashing methods.

Python 3.9.1 (default, May 10 2022, 11:36:26)
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import crypt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.9/crypt.py", line 117, in <module>
    _add_method('MD5', '1', 8, 34)
  File "/usr/lib/python3.9/crypt.py", line 94, in _add_method
    result = crypt('', salt)
  File "/usr/lib/python3.9/crypt.py", line 82, in crypt
    return _crypt.crypt(word, salt)

Brett Cannon daa5799cb8 Make Lib/crypt.py meet PEP 8 standards. This also led to a tweak in the new API 
by making methods() into a module attribute as it is statically calculated.
