[PATCH] Btrfs-progs: Correct path munging in bcp

[cwillu <cwillu@cwillu.com>]

Bcp was assuming that a path on the command line would never have a slash after
it, which is silly, and would cause the first letter of everything in the root
of the source to be truncated.  Instead, use os.path.relpath to handle
it properly.
