m68k: Remove ptrace_signal_deliver
This fixes debugger syscall restart interactions. A debugger that modifies the tracee's program counter is expected to set the orig_d0 pseudo register to -1, to disable a possible syscall restart. This removes the last user of the ptrace_signal_deliver hook in the ptrace signal handling, so remove that as well.
