signal/ia64: Replace FPE_FIXME with FPE_FLTUNK

Browse Source 
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.
