commit 8049474636d1a56cb259af6e527fb6b0a42e43e1

v2v: use .ovf and .mf files anywhere within ova files
Do not rely on .ovf and .mf files being in the top-level of the ova
archive, but search them anywhere within the content of the ova.
This also changes the result of the search of the .ovf file: previously,
one (random) file was picked in case there were more than one, while now
this situation triggers an error.
Related to RHBZ#1186800.
