m/n/core: fix panic logging

We fix a few issues:

 1. Logging to the runtime file descriptors didn't work for some
    reason. Opening the FD(s) manually works.
 2. We didn't log into consoles.
 3. We didn't return errors/results correctly. RawSyscall performs its
    own '>0' check on a syscall result and routes the result to either
    the first or last return value. We need to undo this check to return
    the same unified argument as runtime.write expects and
    runtime.write1 provides.
