CVE-2019-15325 : In GalliumOS 3.0, CONFIG_SECURITY_YAMA is disabled but /etc/sysctl.d/10-ptrace.c

In GalliumOS 3.0, CONFIG_SECURITY_YAMA is disabled but /etc/sysctl.d/10-ptrace.conf tries to set /proc/sys/kernel/yama/ptrace_scope to 1, which might increase risk because of the appearance that a protection mechanism is present when actually it is not.
