[Patch v2] scripts/run-test: Keep original prune behaviour

[<george.zhang@amd.com>]

From: George Zhang <george.zhang@amd.com>

The default prune behaviour of the runner settings was changed.
This change is to maintain the original behaviour of this script
while also enabling the prune mode to be overriden.

Fixes: 997bac8 ("runner/settings: set PRUNE_KEEP_ALL as default")
