signal/alpha: Replace FPE_FIXME with FPE_FLTUNK
Using an si_code of 0 that aliases with SI_USER is clearly the wrong thing todo, and causes problems in interesting ways. The newly defined FPE_FLTUNK semantically appears to fit the bill so use it instead. Given recent experience in this area odds are it will not break anything. Fixing it removes a hazard to kernel maintenance.
