run_*tests*.py: print Meson version at start of test suite

on some systems, tests may take over an hour to run--only to find
you might have used an unintended Meson version (e.g. release instead
of dev). This change prints the Meson version at the start of the
run_*tests*.py scripts.

Also, raise SystemExit(main()) is preferred in general over
sys.exit(main())
