mem: Trigger DRAMCtrl resp queue panic

Tweaks to trigger the panic in DRAMCtrl when its outgoing PacketQueue grows too
large. Specifically, this patch hardcodes a lower max queue size, and modifies
the memtest.py script is changed to use DDR3 memory instead of SimpleMemory.

Here is a command line that triggers the panic:

% build/X86/gem5.opt --debug-flag=DRAM --outdir=$outdir
configs/example/memtest.py -u 100
