std.mem.ValidationAllocator: forward free() calls
Failing to forward free calls to the underlying allocator makes `ValidationAllocator` unusable for testing allocators while checking for leaks. This change allows allocators that wrap `std.testing.allocator` to be tested with `std.heap.testAllocator()` in test decls without reporting erroneous leaks.
