[PATCH] meson: Explicitly specify run_command's check parameter

[Martin Kletzander]

An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change.  It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome.  To make sure the behaviour does not change
specify the parameter explicitly.  In places where we check for the return code
the parameter should be 'false' so that meson does not fail.  In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.

The warning in meson was added in https://github.com/mesonbuild/meson/pull/9304
