utils/android: LogcatMonitor: put pexpect.spawn() in str mode

Browse Source 
By default, pexpect.spawn() is a bytes interface: its read methods
return bytes and its write/send and expect method expect bytes. Logcat
uses utf-8 strings, so put pexpect.spawn() in str mode.

This code can't have worked in python3 before, since the logcat file
is not opened in "b" mode.
