lvmdbusd: Wrap json.load in try/except
In testing where we inject large amounts of additional output in stderr
we can occassionally get truncated stdout from lvm. Catching and dumping
the json for debug before we re-raise the exception. As this doesn't
happen without the error injecting wrapper around lvm, the error seems to
be with the wrapper.
