[libstdc++] Add _GLIBCPP_USE_WCHAR_T guard to testcase

[David Edelsohn]

	The recently added test 22_locale/num_put/put/char/7.cc fails on
AIX due to the testcase referencing "wcout", which is undefined if
_GLIBCPP_USE_WCHAR_T is not defined.

	* testsuite/22_locale/num_put/put/char/7.cc: Guard with
	_GLIBCPP_USE_WCHAR_T.
