busybox: add busybox_git.bb recipe

Add busybox_git.bb recipe so that it would be easier to hack with
busybox. Set DEFAULT_PREFERENCE to "-1" in the git recipe so that we
still use the busybox_1.21.1.bb recipe by default.

+Upstream-Status: Pending
+
+The current behaviour of busybox is to try all fstype when automounting
+even when no media exists.  The util-linux mount command bails when no
+media exists, so change the behaviour of busybox to do the same.
+
+It could also be argued that the KERN_INFO message from btrfs could be
+removed, but that would be harder to accomplish.
