signal/alpha: si_trapno is only used with SIGFPE and SIGTRAP TRAP_UNK
While reviewing the signal handlers on alpha it became clear that
si_trapno is only set to a non-zero value when sending SIGFPE and when
sending SITGRAP with si_code TRAP_UNK.
Add send_sig_fault_trapno and send SIGTRAP TRAP_UNK, and SIGFPE 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.
