asar-tests: fix -Wformat-truncation warning

[orbea]

Gentoo considers this warning to be a QA issue for the ebuild and prints an additional warning.

Please review for correctness, I don't think these need to be 512 and the tests work fine on my end.

[randomdude999]

this entire test runner is gone in 2.0, but doesn't hurt to merge it i guess

(edit: oh hm it's not actually deleted. i think i've now rewritten all of its functionality though, so should be fine to delete)

[randomdude999]

....oh whoops, i thought you targeted this against asar_19. i'll cherry-pick it into there, and possibly soon delete this runner

Thanks, I saw the warning in both places so I decided to do it in the asar_2_beta first.
