em100: Make trace mode output more resilient
When redirecting em100 output to a file, say with | tee <filename>,
we won't see any output from the tool until actual SPI commands are
coming in. This is annoying, as you don't know when the download is
finished, if your workflow is for example as follows:
1. start em100 in trace mode
2. wait for download to em100 to finish
3. power-cycle / turn on the machine
