[Libguestfs] [PATCH] v2v: tests: avoid '..' in member names for tar

[Pino Toscano]

Very recent versions of tar (most probably as a consequence of
CVE-2016-6321) may refuse archive members with '..', like the relative
paths to upper level directories.

Since these are just tests, simply copy the files in the temporary
directories where tar (or zip as well) is run, so all the files are in
the same directory.
