Rename pkg/git to pkg/vcs because we need to support not only git.

+rbtree: include rcu.h
+foobar@foobar.de
+Fri May 11 16:02:14 2018 -0700
+Since commit c1adf20052d8 ("Introduce rb_replace_node_rcu()")
+rbtree_augmented.h uses RCU related data structures but does not include
+the header file.  It works as long as it gets somehow included before
+that and fails otherwise.
