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.
