signal/sparc: si_trapno is only used with SIGILL ILL_ILLTRP
While reviewing the signal handlers on sparc it became clear that
si_trapno is only set to a non-zero value when sending SIGILL with
si_code ILL_ILLTRP.
Add force_sig_fault_trapno and send SIGILL ILL_ILLTRP with it.
Remove the define of __ARCH_SI_TRAPNO and remove the always zero
si_trapno parameter from send_sig_fault and force_sig_fault.
