[PATCH pynfs 06/13] server41tests: test COPY with bad source stateid

Add testCopyBadSourceStateid (COPY8) and a _bad_stateid() helper that
returns a fabricated, non-special stateid -- not the all-zero anonymous
or all-one READ-bypass special stateids, which a server legitimately
accepts -- so the server is forced to reject it with NFS4ERR_BAD_STATEID.
