tools/pyboard.py: Make enter_raw_repl stricter and more reliable. 

When looking for chars to indicate raw repl is active, look for the full
string of chars to improve reliability of entering raw repl correctly.

Previous to this patch there was the possibility that raw repl was
entered in a dirty state, where not all input chars from previous
invocation were drained.
