target-i386/translate.c: mov to/from crN/drN: ignore mod bits

> This instruction is always treated as a register-to-register (MOD = 11)
> instruction, regardless of the encoding of the MOD field in the MODR/M
> byte.

Also, Microport UNIX System V/386 v 2.1 (ca 1987) runs fine on
real Intel 386 and 486 CPU's (at least), but does not run in qemu without
this patch.
