scripts/setlocalversion: factor out 12-chars hash construction
Both of if and else parts append exactly 12 hex chars, but in different ways. Factor out the else part because we need to support it without relying on git-describe. Remove the --abbrev=12 option since we do not use the hash from git-describe anyway.
