If `FrameBufferAllocator::allocate()` causes the construction to be aborted, the allocated `GstLibcameraAllocator` will not be deallocated properly. Use `g_autoptr()` to address this. `g_steal_pointer()` could only be used in glib 2.68 or later because earlier it evaluates to a pointer-to-void in C++, which would necessitate a `static_cast`.
