libstdc++: Fix test failure with --disable-linux-futex

As noted in PR 96817 this new test fails if the library is built without
futexes. That's expected of course, but we might as well fail more
obviously than a deadlock that eventually times out.

libstdc++-v3/ChangeLog:

* testsuite/18_support/96817.cc: Fail fail if the library is
configured to not use futexes.
