[apparmor] [patch] regression swap test: 640 KiB not enough swap for everyone

[Steve Beattie]

On ppc64el platforms, the minimum swapfile size is 640KiB. Our swap
test aborts there because it creates a swapfile of size 512KiB. This
patch adjusts the size to 768KiB, to satisfy ppc64el and to try
to keep the size down for embedded and otherwise limited platforms
(e.g. phones).
