Our test infrastructure allows you to set the TIMEOUT_MULTIPLIER environment variable to raise the test timeouts if you're building for a slow environment. (scripts/mtest2make.py reads it and sets the meson test -t argument accordingly.) Document this so it's not a secret feature only known to a select few.
