[igt-dev] [PATCH i-g-t 08/18] scripts/igt_doc.py: don't use ":=" operator

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

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

As this was introduced on python 3.8, remove its usage, in order
to make the script compatible with version 3.7.

Acked-by: Zbigniew Kempczyński <zbigniew.kempczynski@intel.com>
