Subject: scripts/gdb: fix issue with dmesg.py and python 3.X
When built against Python 3, GDB differs in the return type for its
read_memory function, causing the lx-dmesg command to fail.
Now that we have an improved read_16() we can use the new read_memoryview()
abstraction to make lx-dmesg return valid data on both current Python APIs
Tested with python 3.4 and 2.7
Tested with gdb 7.7
