[PATCH 3/3] status: ignore status.aheadbehind in porcelain formats

["Jeff Hostetler via GitGitGadget" <gitgitgadget@gmail.com>]

From: Jeff Hostetler <jeffhost@microsoft.com>

Teach porcelain V[12] formats to ignore the status.aheadbehind
config setting. They only respect the --[no-]ahead-behind
command line argument.  This is for backwards compatibility
with existing scripts.
