Remove first-boot-set-mac service for IBM machines

- This commit removes the first-boot-set-mac service as the
  similar and a better functionaly is now implemented in
  phosphor-networkd service.

- Here are the few disadvantages of the first-boot-set-mac service
1. The first-boot-set-mac is a script is not scalable with the
   increase in the number of ethernet interfaces.
2. Why do we need a new service just for setting the MAC Address
   when the network service alone can do it , and it makes sense
   to tie up this feature with Network as setting MAC address
   functionality  is implemented and owned by networkd.
3. With first-boot-set MAC, we need to make sure the VPD is populated
   before , if for any reason the VPD  is not generated the first-boot
   service cannot help set the MAC.
