flush stdout before starting a command while interactive
Summary:
Now that the subprocess output is no longer piped, we can see a weird situation
where the command being run is displayed after the compilation step:
+ cd /data/users/xavierd/scratch/dataZusersZxavierdZfbsource/fbcode_builder_getdeps/build/eden && \
[1/13] rust_job_pool

This is a bit awkward. Flushing stdout's buffer allows for the ordering to be
correct.
