Postci fails to launch get_host_info.sh

[Gabriele Cerami]

Periodic jobs that fail have postci logs almost empty.

An error is shown:

apparently the version of sudo on the host does not support the --preserve-env long option

Since this bug halts logs collection, there's no other way to understand why a build failed. this bug should be marked as urgent
