[PATCH i-g-t] meson.sh: allow making it less verbose

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

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

Add support for not output each build step and run ninja
with --quiet option.

This is interesting specially when executed inside some
script.
