scripts/dump-guest-memory.py: Improve python 3 compatibility 

This commit does not make the script python 3 compatible, it is a
preparation that fixes the easy and common incompatibilities.

Print is a function in python 3 and therefore needs braces around its
arguments.

Range does not cast a gdb.Value object to int in python 3, we have to
do it ourselves.
