gdb(4) fix x86 signal reporting

Description

gdb(4) fix x86 signal reporting

The existing values correspond to x86 exception vector numbers, but the
trap numbers used in the kernel do not match these 1-to-1. Prefer the
definitions from x86/trap.h, as they are what actually get passed to
kdb_trap(). This is of little consequence, as gdb_cpu_signal() only
reports the trap reason (signal number) to the gdb client.

This is limited to the subset of trap values for which kdb_trap() is
reachable.
