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.

+#    busybox: update appletlib dependency patch
+#    
+#    Previous version still failed from time to time on clean-start builds
+#    with 4 bitbake threads and '-j16'. Building busybox as sole target worked
+#    well.
+#    
+#    The reason is that previous version introduced a race between applets make
+#    processes spawned from top-level Makefile and from libbb Makefile.
+#    
+#    Fix it with high-level dependency that doesn't create races.
