ipmi-whitelist:Allow set securitymode cmd from KCS

Issue: Issuing set security mode for Provisioned Host Disabled command
       is restricted from KCS channel.

Fix: Allow set security mode command execution from KCS interface by
     adding channel mask in ipmi-whitelist.conf

Tested:
Verified using ipmitool raw command from Linux OS
1. Set restriction mode as ProvisionedHostWhitelist
Command: busctl set-property xyz.openbmc_project.RestrictionMode.Manager
         /xyz/openbmc_project/control/security/restriction_mode
         xyz.openbmc_project.Control.Security.RestrictionMode
                    RestrictionMode s
         "xyz.openbmc_project.Control.Security.RestrictionMode.Modes.
           ProvisionedHostWhitelist"
Response:               //Success
2. Check the restriction mode
Command:  ipmitool raw 0x30 0xb3
Response: 04 00
3. Execute set security mode for Provisioned Host Disabled command from
   Linux OS terminal
Command:  ipmitool raw 0x30 0xb4 0x5
Response:                  //Success
