Don't explicitly set clone child ptrace options
linux_handle_extended_wait calls target_post_attach if we're handling
a PTRACE_EVENT_CLONE, and libthread_db.so isn't active.
target_post_attach just calls linux_init_ptrace_procfs to set the
lwp's ptrace options. However, this is completely unnecessary,
because, as man ptrace [1] says, options are inherited:
"Flags are inherited by new tracees created and "auto-attached" via
active PTRACE_O_TRACEFORK, PTRACE_O_TRACEVFORK, or PTRACE_O_TRACECLONE
options."
This removes the unnecessary call.
