policycoreutils: audit2* - ignore setlocale errors

When a user has invalid locales set, audit2allow and audit2why fail with
a traceback. This could be safely ignored as it will stay with 'C'
locale.

Fixes:
Traceback (most recent call last):
  File "policycoreutils/audit2allow/audit2allow", line 35, in <module>
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib64/python2.7/locale.py", line 579, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
