tools/testing/selftests/mm/run_vmtests.sh: lower the ptrace permissions
On Ubuntu and probably other distros, ptrace permissions are tightend a
bit by default; i.e., /proc/sys/kernel/yama/ptrace_score is set to 1.
This cases memfd_secret's ptrace attach test fails with a permission
error. Set it to 0 piror to running the program.
