Set O_APPEND mode for stdout/stderr and output-sync temporary files. POSIX does not guarantee that writes will be atomic if a file is opened for normal (non-append) output. That means if multiple processes are writing to the same file, output could be lost. I can't think of a real use-case where we would NOT want append for stdout/stderr, so force it if we can.
