  m68k: fix 'bkpt' instruction in softmmu mode

In linux-user mode, 'bkpt' generates an EXP_DEBUG exception to allow
QEMU gdb server to intercept and manage the operation with an external
debugger.

In softmmu mode, the instruction must generate an illegal instruction
exception as it is on real hardware to be managed by the kernel.
