exception: add errno for all exceptions
sd_bus maintains an errno for all exceptions. There are some
users of the library that are catching an SdBusError because they
want an easy way to change to an errno, but as a result they are
potentially missing exceptions. Add the `get_errno` method into
our base exception object and return the same default that sd_bus
uses: EIO.
