When running the tests without pre-compiled headers
(--disable-libstdcxx-pch), the test fails, because the feature
testing macro (FTM) isn't defined yet.

This commit moves checking the FMT to a dedicated file (version.cc)
that's run without PCH.

libstdc++-v3/ChangeLog:

        * testsuite/20_util/function_objects/not_fn/nttp.cc: Move
        test of feature testing macro to version.cc
        * testsuite/20_util/function_objects/not_fn/version.cc: New test.
