tools: fflush the output in debug-events after each set of events

Fixes e.g. the case where debug-events is used to get the initial device
list but no more. Since we never flush, the content is stuck in the
buffers and gets lost.

Easy way to reproduce: `libinput debug-events | cat`, then ctrl+c and see
nothing show up (before this patch, anyway).
