auto: increment beta version to 17.0.291

Because exitProcess is async, static analysis of the function does not
show process termination, even though it returns Promise<Never>. This
can lead to compiler warnings when it gets confused about missing return
values. So have moved to always returning the value from exitProcess,
even though it will never actually return!
