[igt-dev] [PATCH i-g-t 11/18] scripts/igt_doc.py: use a different logic to get IGT prefix

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

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

The past logic was dependent on how the initial Xe IGT support
was conceived. Change it to be more generic and use
os.path.commonprefix.
