In write_patterns_and_update(), we always need to free the pattern list
before exiting the function. Rather than handling it manually when we
return early, we can jump to an "out" label where cleanup happens. This
let us drop one line, but also establishes a pattern we can use for
other cleanup.

This would also be helpful in the long run if all of the other die()
calls ended up as error returns, but I guess this is in builtin/, so it
may not be that likely a candidate for libification anyway.
