Improve some runtime struct layouts
Guided by pahole, I've shaved off a few padding bytes here and there.
New sizes on x86_64:
stap_task_finder_target 192 -> 184
stap_itrace_probe 216 -> 208
stap_utrace_probe 328 -> 312
stap_uprobe_tf 200 -> 192
stap_uprobe_spec 48 -> 40
I only changed field layouts, not types or names, so this should be
perfectly safe. (FLW)
