Allow keeping vendor subdirectories in vendored packages
Allow keeping vendor subdirectories in vendored packages

github.com/coreos/etcd as of v2.2.5 uses a Godeps subdirectory, and
imports packages by including the Godeps path fragments directly in the
package name; so we can't just remove the subdirectory and vendor the
included package directly.  So, add a flag to clone() to surpress
removing the vendor subdirectories.
