setlocalversion: sync with Linux kernel version (2.6.34)

Brings a number of fixes, and most importantly no longer tries to figure
out if the tree contains uncommitted changes when using svn, as that can
be very slow.

This only syncs with setlocalversion as of 2.6.34 as later kernel versions
aren't directly compatible with our use cases since 09155120c (kbuild:
Clean up and speed up the localversion logic).

We still have one delta from the kernel version (setlocalversion: fix i18n
issue with svn), as that has only later been fixed in the kernel version.
