shell-test: remove REP_NODELAY, less delay with REP

REP_NODELAY was added because REP delayed too much.  This changes REP to
only add a delay on every 100th line instead.

This helps to cover the additional pulse steps with
out_data_decide_throttle, which would have required to change
REP_NODELAY anyway.
