kernel-yocto: export GUILT_BASE to devshell

One of the patch backends to linux-yocto is guilt, which normally
tracks patches under .git. But .git isn't something that can be
checked into a SCM and repeated. So it has been moved under meta/patches
and committed to the meta branch.

If devshell is used, GUILT_BASE isn't set, so patch manipulations will
fail. We export GUILT_BASE and point it at the meta directory when
devshell is invoked for linux-yocto.
