units: add a basic SystemCallFilter (#3471)
Add a line SystemCallFilter=~@clock @module @mount @obsolete @raw-io ptrace for daemons shipped by systemd. As an exception, systemd-timesyncd needs @clock system calls and systemd-localed is not privileged. ptrace(2) is blocked to prevent seccomp escapes.
