fault-monitor: Catch GetSubTree exceptions

The C++ implementation of the mapper will throw an exception
if the passed in interface was not found on any paths, which
is expected to happen when fru-fault-monitor checks for error
logs on startup and there aren't any.  Catch that exception
and just continue on the path of there being no error logs.

Note this is made slightly more complicated by the fact that the
default constructor for sdbusplus::message is deleted, so one
cannot just do:

sdbusplus::message reply;
try
{
    auto method = bus.new_method_call(...);
    reply = bus.call(method);
}
...
reply.read(...);
