SETroubleshoot SafeConfigParser Depreciation Fix

[jjbyrnes29]

In setroubleshoot-3.3.23, lines 41 to 44 of config.py.in contain the lines:

try:
 from configparser import SafeConfigParser
except ImportError:
 from configparser import SafeConfigParser

SafeConfigParser has been depreciated in Python 3.12 as per
python/cpython#92503

In testing, I was able to get the package to be built by editing SafeConfigParser to ConfigParser
