manifest: relax include name rules for user-specified pathv2.13.1

Allow the user to specify relative or absolute or any other funky
path that they want when using `repo init` or `repo sync`.  Our
goal is to restrict the paths in the remote manifest git repo we
cloned from the network, not protect the user from themselves.
