linux-user/nios2: Fix EA vs PC confusion
The real kernel will talk about the user PC as EA,
because that's where the hardware will have copied it,
and where it expects to put it to then use ERET.
But qemu does not emulate all of the exception stuff
while emulating user-only. Manipulate PC directly.
This fixes signal entry and return, and eliminates
some slight confusion from target_cpu_copy_regs.
