Fix breakpoint support in Nios II user-mode emulation.

Browse source 
Nios II user-mode emulation was missing handling for EXCP_DEBUG,
making the gdb stub essentially useless.  This patch adds the missing
piece.  The new code was copied from the existing EXCP_TRAP handling
and is also similar to what other targets (e.g., arm) do with EXCP_DEBUG.
