adjust MessageOutput for changes in espressif/arduino-esp32

Browse Source 
the "serial console" over USB would be garbled badly after switching to
"platform = espressif32@6.7.0". this did not happen to the upstream
version of MessageOutput. we used Serial.flush(), which seemed to be
good in the respective context. however, the changes in

github.com/espressif/arduino-esp32/pull/9462

made flush() detrimental. we remove the use of flush(), as it seems not
to be required (in particular, the upstream project does not use it).
