qemurunner.py: ignore decode errors

qemu output can contain control characters. This cause qemurunner
API to crash when decoding the output to utf-8:

Traceback (most recent call last):

    msg = msg.decode("utf-8")
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xda in position 0:
unexpected end of data

Added errors='ignore' to decode call to fix this.
