[PATCH v2] libstdc++: Fix preprocessor check for __float128 formatter [PR119246]

The previous check `_GLIBCXX_FORMAT_F128 != 1` was passing if _GLIBCXX_FORMAT_F128 was not defined, i.e. evaluted to zero. This broke sparc-sun-solaris2.11 and x86_64-darwin. PR libstdc++/119246 libstdc++-v3/ChangeLog: * include/std/format: Updated check for _GLIBCXX_FORMAT_F128
