repair: make paths in "_bundle()" relative to ".hg"
This patch makes paths below in "_bundle()" relative to ".hg":
- backup directory ("strip-backup"), and
- bundle file under backup directory
"vfs" is passed to "changegroup.writebundle()" to use relative path
directly.
This patch applies "vfs.join()" on the value returned by "_bundle()",
because the caller expect it to return absolute path.
This will be changed by succeeding patch changing the caller side.
