[PATCH v1 2/2] perf test attr: Fix deprecation warning

[Ian Rogers]

Address the warning:
```
tests/attr.py:155: DeprecationWarning: The SafeConfigParser class has
  been renamed to ConfigParser in Python 3.2. This alias will be
  removed in Python 3.12. Use ConfigParser directly instead.
parser = configparser.SafeConfigParser()
```
by removing the word 'Safe'.
