[Libguestfs] [PATCH] v2v: fix directory check for virtio-win as directory

[Pino Toscano]

When trying to install files from virtio-win as directory, check for
directory existance using absolute paths.  Otherwise, is_directory is
called on relative paths such as "linux/el7" which obviously do not
exist.

Fixes commit 1c85b64c1c3a4d5267b952102375cb78f18a85c4.
