On AIX printf formats a quiet NaN as "NaNQ" and it doesn't matter
whether %f or %F is used. Similarly, it always prints "INF" for
infinity, even when %f is used. Adjust a test that currently fails due
to this AIX-specific (and non-conforming) behaviour.
libstdc++-v3/ChangeLog:
* testsuite/22_locale/num_put/put/char/lwg4084.cc [_AIX]: Adjust
expected output for NaN and infinity.

Tested x86_64-linux and powerpc-aix.
Pushed to trunk.
