git-core provides the following routines (among others): git-sh-setup,
cd_to_toplevel, die, and more.  But it is not always in the same location
relative to the guilt binary if git is not part of a 'host tools'
sysroot. Modern git versions don't need this, so commenting it out (until it
breaks again) is the solution to the problem of it not existing, and the
library routines will sourced and provided by git itself.

Since bitbake.conf has git-native as ASSUME_PROVIDED, this means that
when the system git binary is used, errors such as this can be seen in
failed patch logs:

With the export removed, we have a normal "clean" failure message when
the sysroot or system git is used.

Updating guilt to allow git 1.8.x as a supported version. This version has
no impact on other functionality within the scripts, so no other adjustments
are necessary.

The kernel.org mirror of the guilt tarball has been missing for a while
and the yocto mirrors have been keeping builds working. Switching to a
debian upstream is better than solely relying on the yocto mirrors for
serving the tgz.

* We have various variables which are either not quoted at all or are half
  quoted. This patch fixes the bad exmaples so everything is consistent.

For some reason guilt-native seems to have gone out of its way to refer explicitly to /usr, which breaks on micro.
Let's use ${prefix} instead.

In mirrors.bbclass we point into /pub but we don't in bitbake.conf.
All uses of KERNELORG_MIRROR look into /pub anyhow, so lets make
use of that.
