Libguestfs - Jan 2023 - [v2v PATCH 2/2] test-v2v-i-ova: spell out ntfs feature group dependency

"windows.img" is created as an empty phony image if the libguestfs
appliance lacks the ntfs feature group.

"tests/Makefile.am" deals well with this, because for the
"central"
"windows.vmdk" target, we restrict the VMDK conversion to a non-empty
"windows.img". Subsequently, dependent test cases check for
"windows.vmdk"
specifically, and if that file is missing, the tests are skipped (they
exit with code 77).

"test-v2v-i-ova.sh" and "test-v2v-i-ova-directory.sh" are
exceptions
however. They perform the same conversion manually (in their own separate
workspace directories). They assume that, if "windows.img" exists, it
can
be converted to VMDK. When the image size is zero, the conversion breaks,
and both test cases fail. Skip both tests if "windows.img" is empty.

Looks good, series ACK, thanks!
