signal/alpha: Replace TRAP_FIXME with TRAP_UNK
Using an si_code of 0 that aliases with SI_USER is clearly the wrong
thing to do, and causes problems in interesting ways.
For it really is not clear to me if using TRAP_UNK bugcheck or
the default case of gentrap is really the best way to handle
things. There is certainly enough information that that a more
specific si_code could potentially be used. That said TRAP_UNK
is definitely an improvement over 0 as it removes the ambiguiuty
of what si_code of 0 with SIGTRAP means on alpha.
Recent history suggests no actually cares about crazy corner cases of
the kernel behavior like this so I don't expect any regressions from
changing this. However if something does happen this change is easy
to revert.
