linux-user/nios2: Hoist pc advance to the top of EXCP_TRAP

Note that this advance *should* be done by the translator, as
that's the pc value that's supposed to be generated by hardware.
However, that's a much larger change across sysemu as well.

In the meantime, produce the correct PC for any signals raised
by the trap instruction.  Note the special case of TRAP_BRKPT,
which itself is special cased within the kernel.
