misc: Move the ExitLogger class definition into misc.cc

This class isn't referred to outside of misc.hh, and isn't necessarily
useful outside of the particular logging setup implemented in misc.cc.
The Logger class itself is different since it provides a generic
interface that can be used with different logging schemes.
