sim: fixes for libopcodes styled disassembler

  commit 60a3da00bd5407f07d64dff82a4dae98230dfaac

      objdump/opcodes: add syntax highlighting to disassembler output

I broke several sim/ targets by forgetting to update their uses of the
libopcodes disassembler to take account of the new styled printing.

These should all be fixed by this commit.

I've not tried to add actual styled output to the simulator traces,
instead, the styled print routines just ignore the style and print the
output unstyled.
