OVA not a real standard.  Colour me surprised ...

[Libguestfs] [PATCH 2/5] v2v: -i ova: Allow directories and ZIP files to be used as input (RHBZ#1152998).

OVA is not a particularly well-specified format.  The specification
allows a directory to be an OVA, so enable that.  The spec doesn't
mention that ZIP can be used in place of tar, but since we have seen
these in the wild, allow that too.
