scripts/gdb: fix lx-timerlist for Python3
Below incompatibilities between Python2 and Python3 made lx-timerlist fail
to run under Python3.
o xrange() is replaced by range() in Python3
o bytes and str are different types in Python3
o the return value of Inferior.read_memory() is memoryview object in
Python3
akpm: cc stable so that older kernels are properly debuggable under newer
Python.
