libstdc++: Fix accidental duplicate test [PR91456]
It looks like I committed the testcase for std::function twice, instead
of one for std::function and one for std::is_invocable_r. This replaces
the is_invocable_r one with the example from the PR.
libstdc++-v3/ChangeLog:
PR libstdc++/91456
* testsuite/20_util/function/91456.cc: Add comment with PR
number.
* testsuite/20_util/is_invocable/91456.cc: Likewise. Replace
std::function checks with std::is_invocable_r checks.
