Subject: scripts/gdb: decode bytestream on dmesg for Python3
The recent fixes to lx-dmesg, now allow the command to print
successfully on Python3, however the python interpreter wraps the bytes
for each line with a b'<text>' marker.
To remove this, we need to decode the line, where .decode() will default
to 'UTF-8'
