Calculate the version ID of BMC UBI volumes during build time.

- When the new ubi layout is flashed onto the BMC, the volumes
  were named kernel-0 and rofs-0 by default. This tends to be
  misleading as we can't differentiate between two different BMC
  versions.
- Now the ubi volumes will be named kernel-<versionID> and
  rofs-<versionID> calculated by getting the hash(SHA-512) of
  the version and taking the first 8 characters.
- The Uboot env needs to be updated to point to the correct
  kernelname which has now changed from kernel-0 to
  kernel-<versionID> calculated by getting the HASH(SHA-512)
  of the version and taking the first 8 characters.
