[PATCH] Fix test memory_resource to work without sized deallocation

[Jonathan Wakely]

The checking memory_resource in the testsuite assumes sized deallocation
is supported, which might not be true for other compilers.

        * testsuite/util/testsuite_allocator.h (__gnu_test::memory_resource)
        [!__cpp_sized_deallocation]: Do not pass size to operator delete.

Tested powerpc64le-linux, committed to trunk.
