tests: run-tests.sh: ensure non-zero exit when $failed != 0

POSIX [1] does not specify the behavior of `exit' with arguments
outside the 0-255 range, but what generally (bash, dash, zsh, OpenBSD
ksh, busybox) seems to happen is the shell exiting with status & 255
[2], which results in zero exit for certain non-zero arguments.
