[PATCH i-g-t v2 4/4] scripts/igt_doc.py: fix intelci testlist join logic

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Joining testlists shall take into account default values for GPUs
that are defined only on some JSON config files.

Add a logic to propagate such values.
