Setting SEAL_WRITE is not possible if there're pending GUP users. This commit adds selftests for memfd+sealing that use FUSE to create pending page-references. FUSE is very helpful here in that it allows us to delay direct-IO operations for an arbitrary amount of time. This way, we can force the kernel to pin pages and then run our normal selftests.
