Andrey Vagin ed5f540c99 zdtm: add new test case for testing logic about COW memory (v2)

This test tests the following combinations:

1. parent and child have a cow-ed mapping
2. parent and child have just coinciding mappings

the pages state in both should be in all possible combinations of

 a. write mapped
 b. read mapped
 c. not touched
 d. before fork
 e. after fork

v2: * wait until a child are not prepared
    * check a FILE | PRIVATE mappings
