  [lldb] Fix TestProcessIOHandlerInterrupt.py for macos

On darwin, we don't completely suppress the signal used to interrupt the
inferior. The underlying read syscall returns EINTR, which causes premature
termination of the input loop.

Work around that by hand-rolling an EINTR-resistant version of getline.
