[patch] Fix tests that fail with old std::string

[Jonathan Wakely]

These tests only work with the new std::string, but the preprocessor
test was in the wrong place.

Tested powerpc64le-linux, committed to trunk.

    Fix tests that fail with old std::string
    
    	* testsuite/21_strings/basic_string/allocator/char/minimal.cc: Guard
    	explicit instantiation with check for new ABI.
    	* testsuite/21_strings/basic_string/allocator/wchar_t/minimal.cc:
    	Likewise. Use wchar_t as char_type.
