This is an unfortunate order of precedence, because it's frequently handy to be able to override the default by setting an environment variable at the top level of a build or CI invocation. Fortunately, we can flip the order for our purposes, because we always invoke 'meson test' indirectly. We currently invoke 'meson test' passing it a --num-processes argument based on whatever the '-j' option to make was. Adjust the logic in mtest2make so that if MESON_TESTTHREADS is set then we honour that, and don't override it.

One theory for why this is happening is that we're running too many tests in parallel and so sometimes a test gets starved of CPU and isn't able to complete within the timeout. Set the MESON_TESTTHREADS environment variable to 1 for this job; this will cause 'meson test' to run only one test at a time. (Note that this relies on the change to meson2make that makes it honour MESON_TESTTHREADS; otherwise it will have no effect.)
