description:
Update TODO.ptrace

Removed:
  - evaluate equivalent for PTRACE_O_TRACECLONE from Linux

clone(2)-like calls are traced with PTRACE_FORK, PTRACE_VFORK and
PTRACE_VFORK_DONE. VFORK ones block parent till termination or execve(2) of
its child.

Added:
  - add proper implementation of PTRACE_VFORK for vfork(2)-like events

Currently PTRACE_VFORK is a stub.
