linux-user: report signals being taken in strace output
Native strace reports when the process being traced takes a signal:
--- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=0} ---
Report something similar when QEMU is doing its internal strace of
the guest process and is about to deliver it a signal.
