uprobe/uretprobe tests don't do any validation of arguments/return values, and without this we can't be sure we are attached to the right function, or that we are indeed attached to a uprobe or uretprobe. To fix this record argument and return value for auto-attached functions and ensure these match expectations. Also need to filter by pid to ensure we do not pick up stray malloc()s since auto-attach traces libc system-wide.
