qcacld-3.0: Include commits since checkout in build tag
Currently, only the Change-Id for HEAD is included in the build tag.
This can be problematic for builds which include hotfixes
(cherry-picks). Include the Change-Ids of every cherry-pick commit since
the last non-cherry-pick commit. This allows developers to quickly
identify the checkout point used to make the build, as well as any
hotfixes applied.
