vboot-utils: Add update check
https://github.com/void-linux/void-packages/pull/28510

Description:
Adds an update check that parses the git revision.  Also removes the need to keep track of a separate git hash.  Resolves complaint surfaced in #28507, but does not actually update the package as I have no time nor resources to test the functionality of this package.
