Subject: [PATCH] v2v: handle subfolders in ova files

Some ova files like those produced by SUSE Studio have their ovf, mf
and other files inside a folder rather than at the root of the
tarball. Consider the paths relative to the ovf and mf files to cover
this case too.

(cherry picked from commit 9de9300e8b7a99fa06e290f20ef1aaa1eb6f7431)
