meta-phosphor: Improve kernel version string
The kernel version string by yocto by default is <tag>-<revision>, e.g.
5.0.7-b1b37a25644213428f4bab4c427581dd923e35da
Where the revision is the version specified by SRCREV, no matter if
there are additional pathces applied or not.
This commit improves it by
* If there are no yocto patches, keep the current version but use a
shorter revision, e.g. 5.0.7-b1b37a2
* If there are yocto patches, append -dirty-<new-short-revision> to the
version string, e.g. 5.0.7-b1b37a2-dirty-84fa553
Resolves openbmc/openbmc#1289
Tested: Verify the kernel version string is changed as above depending
on if there are yocto patches.
