Joel Fernandes (Google) 2e53c4e1c8 memfd: add test for COW on MAP_PRIVATE and F_SEAL_FUTURE_WRITE mappings 
In this test, the parent and child both have writable private mappings.
The test shows that without the patch in this series, the parent and
child shared the same memory which is incorrect.  In other words, COW
needs to be triggered so any writes to child's copy stays local to the
child.
