torture: Specify qemu memory size with --memory argument
The 512 megabyte memory size has served quite well, but more memory
is required when using large trace buffers on large systems. This
commit therefore adds a --memory argument to the kvm.sh script, which
allows the memory size to be specified on the command line, for example,
"--memory 768", --memory 800M", or "--memory 2G".
