phosphor-ipmi-config: Handle an empty commit number

The VERSION_ID may not have a commit number for the cases a tag
is created, ex: 2.10.1. Since the code is expecting a commit
number of 1-4 digits, use a '0' if no commit number exists.

Tested: Created a tag 2.10.99 which sets VERSION_ID=2.10.99.
        Without this change, build fails with:
        "Exception: IndexError: list index out of range"
        With this change there are no build errors.
