[libc++][test] Fix new_delete_resource.pass.cpp by passing correct size to deallocate

[cpplearner]

memory_resource requires that the value passed to deallocate matches the argument of allocate ([mem.res.private]/4). Apparently this matters for ASAN (see https://lab.llvm.org/buildbot/#/builders/168/builds/20464).
