Andrey Vagin 6201096cea zdtm: fix a race condition during concurrent execution of tests 
When tests are executed concurrently all of them use
the same root, so libraries must be copied atomically.

Without this patch we can get errors like this:
cp: cannot create regular file ‘/tmp/criu-root.m45u5Y/lib64/ld-linux-x86-64.so.2’: File exists
