For some applications, such as applications that uses huge pages, we might want to have a different mountpoint, for which we pass mount flags that better match our usecase. Therefore, create a new function `drm_gem_object_init_with_mnt()` that allow us to define the tmpfs mountpoint where the GEM object will be created. If this parameter is NULL, then we fallback to `shmem_file_setup()`.
