android: pythonthreefication kicks to stack.py

These changes made the stack tool work for me without hanging
and crashing in Python3.

I did not inspect the surrounding code and did not test with other tools
from bin/, YMMV.

Also I was confused with these things done by the tool:

1. Copying its input to the output before processing it. :butwhymeme:
   - removed this printing

2. Ignoring EOF
   - change it to stop processing input when encountering EOF (i.e.
     pressing Ctrl+D ends the session quietly)

3. Waiting for a line "not looking like backtrace" to start symbolizing
   - clarified this in the welcome message

      # Now paste a crash from logcat.

Bug: None
