Remove PtraceRead error message.
This error message has no meaning and makes it look like an unwinding
failure occurred. These messages are showing up more often now
that a lot more of debuggerd is using the ReadWord and Read calls.
If a higher level function wants to indicate there is an error, then
it can add a more meaningful error.
