Temporary pin cpio to lower version in build iso
Temporary pin cpio to lower version in build iso

As a temporary workaround, when build_fuel_iso is set to true
on jenkins slave, install '2.11+dfsg-1ubuntu1' version of cpio
to prevent issue with sysmlinking during the iso build.

A proper fix is to be prepared by the build team, in a next 2-3
weeks from now.
