[libunwind] Adjust the signal_frame test for Arm

Summary:
This patch adjusts the signal_frame.pass.cpp to pass on Arm targets:
* When Arm EHABI is used the unwinder does not use DWARF, hence the
  DWARF-specific check unw_is_signal_frame() must be disabled.
* Certain C libraries don't include EH tables, so the unwinder must
  not try to step out of main(). The patch moves the test code out of
  main() into a separate function to avoid this.
