We have FAILs in two tests that use { target c++11 } but don't
actually compile in C++11 mode. One because default member
initializers make the type a non-aggregate so it can't be
list-initialized and one because it uses std::less<>.
There are also some tests for container adaptors which should not run
in C++98 mode.
Tested powerpc64le-linux, as c++{98,11,14,17}.
Committed to trunk.

Fix libstdc++ testsuite failures in C++98 and C++11 mode
* testsuite/23_containers/list/operations/78389.cc: Fix for C++11
mode.
* testsuite/23_containers/priority_queue/requirements/constructible.cc:
Mark as unsupported in C++98 mode.
* testsuite/23_containers/queue/requirements/constructible.cc:
Likewise.
* testsuite/23_containers/stack/requirements/constructible.cc:
Likewise.
* testsuite/25_algorithms/make_heap/movable.cc: Fix for C++11 mode.
