[RFA/sparc] Fix step-bt.exp: backtrace after second instruction step

Subject: [RFA/sparc] Fix step-bt.exp: backtrace after second instruction step

Hello,

I encountered on sparc the same problem I saw on i386: When scanning
a function prologue, if an instruction is replaced by a breakpoint,
we read the breakpoint instead of reading the original instruction.

Fixed using the same method as in i386...

        * sparc-tdep.c (sparc_fetch_instruction): Read instruction
        using read_memory_nobpt.

Tested on sparc-solaris, no regression, and fixes one FAIL in
step-bt.exp.

OK to apply?
