  Conditionally check nl_langinfo in locale coercion tests

The problem with dynamically adaptive tests is that they
can sometimes pass without actually testing anything useful.

On Linux and Mac OS X, if setlocale works, we also expect
nl_langinfo(CODESET) to *always* work for the coercion target
locales. The tests now reflect this by always assuming the
target locale will work if setlocale succeeds when running
on Linux or Mac OS X.
