[Dumpsys CLI] Remove Exception bounds on LogBufferEulogizer

LogBufferEulogizer previously used `<T : Exception>` as a generic bound
for its `record` method, but that doesn't seem necessary, since any
`Throwable` would work. The method is used in situ when an exception
is being handled, so that the handler can record the exception and
still throw it.

This change relaxes the bounds to `Throwable` and removes the one place
that was filterig out non-exception throwables in SystemUIService.
