runtime: prevent deadlock when profiling signal arrives in stack scan Precise stack scan needs to unwind the stack. When it is unwinding the stack, if a profiling signal arrives, which also does a traceback, it may deadlock in dl_iterate_phdr. Prevent this deadlock by setting up runtime_in_callers before traceback.
