Mark Brown ba78585585 selftests/mm: check for YAMA ptrace_scope configuraiton before modifying it
When running the memfd_secret test run_vmtests.sh unconditionally tries
to confgiure the YAMA LSM's ptrace_scope configuration, leading to an error
if YAMA is not in the running kernel:

# ./run_vmtests.sh: line 432: /proc/sys/kernel/yama/ptrace_scope: No such file or directory
# # ----------------------
# # running ./memfd_secret
# # ----------------------

Check that this file is present before trying to write to it.

The indentation here is a bit odd, and it doesn't seem great that we
configure but don't restore ptrace_scope.
