[docker-macsec]: Add dependencies of MACsec (#11770)

Why I did it
If the SWSS services was restarted, the MACsec service should also be restarted. Otherwise the data in wpa_supplicant and orchagent will not be consistent.

How I did it
Add dependency in docker-macsec.mk.

How to verify it
Manually check by 'sudo service swss restart'.

The MACsec container should be started after swss, the syslog will look like
