[PATCH] perf tests: Fix SafeConfigParser deprecation warning

[James Clark <james.clark@arm.com>]

The following command:

  perf test attr -vvv

Results in this deprecation warning:

  ./tests/attr.py:142: DeprecationWarning: The SafeConfigParser class
  has been renamed to ConfigParser in Python 3.2. This alias will be
  removed in future versions. Use ConfigParser directly instead.

The last Python 3.2 release was in 2013 and Rhel-6 has Python 3.3 so I
think it's safe to make the replacement now.

Tested with Python 3.8
