Getting the scmversion using scripts/setlocalversion currently only
works when run at the root of a git or mecurial project. This was
introduced in commit 8558f59edf93 ("setlocalversion: Ignote SCMs above
the linux source tree") so that if one is building within a subdir of
a git tree that isn't the kernel git project, then the vermagic wouldn't
include that git sha1. However, the proper solution to that is to just
set this config in your defconfig:

  # CONFIG_LOCALVERSION_AUTO is not set

which is already the default in many defconfigs:

  $ grep -r "CONFIG_LOCALVERSION_AUTO is not set" arch/* | wc -l
  89

So let's bring back this functionality so that we can use
scripts/setlocalversion to capture the SCM version of external modules
that reside within subdirectories of an SCM project.
