Update TODO.ptrace

Remove entries:
  - research support PT_SYSCALL & PT_STEP combined like in Linux
  - GDB Remote Protocol expects a case with a step with a signal to be sent,
    this is currently unsupported on NetBSD

Implemented as PT_SETSTEP and PT_CLEARSTEP.

Remove:
  - support QPassSignals (PT_SET_SIGPASS/PT_GET_SIGPASS) in the kernel, a way to
    stop routing a set of signals to tracer as they are uninteresting - GDB and
    LLDB expect this feature

This interface has been abandoned and will be handled on the debugger level.
