[XEN PATCH] automation/eclair: allow parameter name "unused"

[Federico Serafini <federico.serafini@bugseng.com>]

Update ECLAIR configuration of MISRA C:2012 Rule 8.3 to deviate
violations involving parameter name "unused":
it makes explicit the intention of not using the parameter within
the function.
