[PATCH] Fix scripts/setlocalversion with git

[Nico Schottelius]

Hello!

When using trees like wireless-testing, which have untagged tags,
scripts/setlocalversion does not display any git indication for
localversion.

This patch fixes it: If git is available, but no usable tag is found,
it uses -g${head}. It skips the detection of unanottated tags via
git name-rev.

Please apply, otherwise testers like me always have '2.6.29' for trees
with unanottated tags, instead of 2.6.29-20318-g9aa4755, which helps
a lot if you've tons of kernels installed from different trees.

Sincerly,

Nico
