libtracefs: Fix tracefs_synth_echo_cmd()
The update to use dynamic_events instead of synthetic_events for echoing
the synthetic event missed out on adding the colon, and made the output
incorrect for the new format.

Fixes: d7c5dbb7a231e ("libtracefs: Use the internal dynamic events API when creating synthetic events")
