journald: add CAP_MAC_OVERRIDE in journald for SMACK issue
systemd-journald check the cgroup id to support rate limit option for
every messages. so journald should be available to access cgroup node in
each process send messages to journald.
In system using SMACK, cgroup node in proc is assigned execute label
as each process's execute label.
so if journald don't want to denied for every process, journald
should have all of access rule for all process's label.
It's too heavy. so we could give special smack label for journald te get
all accesses's permission.
'^' label.
When assign '^' execute smack label to systemd-journald,
systemd-journald need to add CAP_MAC_OVERRIDE capability to get that smack privilege.
so I want to notice this information and set default capability to
journald whether system use SMACK or not.
because that capability affect to only smack enabled kernel
