mmc: Create a symlink for HBB to its LID file

With the eventual switch for the host firmware to use PLDM, the vpnor
partition files would not exist anymore. As a temporary transition, need
to create a symlink from HBB to its LID file for the existing mboxd
process to load the data into memory. Eventually, a new lightweight
application would load the contents of this LID file into memory, at
which point this symlink could be removed.

Additionally, the vpnor partition names and their corresponding LID
numbers will be read via a json file as part of the PLDM transition, so
this hardcoded LID number can be dynamically be determined at that
point.

Tested: Verified symlink got created in Rainier and it booted to OS.
