seccomp: Constify sysctl subhelpers
The read_actions_logged() and write_actions_logged() helpers called by the
sysctl proc handler seccomp_actions_logged_handler() are already expecting
their sysctl table argument to be read-only. Actually mark the argument
as const in preparation[1] for global constification of the sysctl tables.
