app_process: += libutilscallstack

app oneway spam notification showing like this:

10-18 13:10:34.022167 10290 30064 30094 W IPCThreadState:
CallStack::getCurrentInternal not linked, returning null
10-18 13:10:34.022253 10290 30064 30094 W oneway spamming:
CallStack::logStackInternal not linked

If we add libutilscallstack into app process, we should be able
to see the callstack of the oneway call offendors.
