tools/memory-model: Move from .AArch64.litmus.out to .litmus.AArch.out

When the github scripts see ".litmus.out", they assume that there must be
a corresponding C-language ".litmus" file. Won't they be disappointed
when they instead see nothing, or, worse yet, the corresponding
assembly-language litmus test? This commit therefore swaps the hardware
tag with the "litmus" to avoid this sort of disappointment.

This commit also adjusts the .gitignore file so as to avoid adding these
new ".out" files to git.
