Update IPMI robot test code with latest directives

Changes:
   - Run KeyWord If is deprecated since Robot
     Framework version 5.*, use 'IF' instead
   - Exit For Loop If is deprecated since Robot
     Framework version 5.*, use
     IF  '${var}' == 'EXIT'  BREAK

Tested:
     - Checked using robot dry-run to make sure the
     syntax is not broken
