bitbake: server/process: Ensure we don't loop on client EOFError

The server currently crashes if we hit an EOFError due to controllersock
still being in ready and the continue meaning ready isn't re-evaluated.
Setting the value to False can mean the shutdown code doesn't handle the
situation cleanly.

Clear ready to avoid the crash/loop instead and handle any OSError whilst
we're in here.
