[CRIU] [PATCHv2 3/4] restore: Create temp proc in /tmp

[Radostin Stoyanov]

When restoring a container with user namespace, CRIU fails to create
a temporary directory for proc. The is because the unprivileged user
that has been just restored does not have permissions to access the
working directory used by CRIU.

Resolves #828
