[PATCH] scripts/setlocalversion on readonly source

From: Christian Kujau

I'm building kernels with O=/some/dir and at some point
scripts/setlocalversion is being called, doing:

+ git update-index --refresh --unmerged
fatal: Unable to create '.git/index.lock': Read-only file system

Not only does it throw this error but it takes quite a long time to run,
only to fail anyway because the kernel source dir is located on a
read-only NFS mount.

The following patch makes the error go away:
