  [lldb/Reproducer] Disable buffering of stdout during replay

Different buffering behavior during capture and replay caused some of
the shell tests to fail when run from a reproducer. By disabling stdout
buffering we get a better approximation of how things get flushed during
an regular debug session. There is a performance impact but since this
only affects replay this is acceptable.
