[PATCH] imagetypes: Set tmpdir for skopeo

[PATCH] imagetypes: Set tmpdir for skopeo

[Anton Mikanovich]

Skopeo stores temporary files in /var/tmp by default.
This can cause following error on copy command:

Error writing blob: write /var/tmp/docker-tarfile-blob454201730: no space left on device

To remove dependence from root filesystem free space set current recipe
workdir as tmpdir for skopeo.
