journal: install sigbus handler for journal tools too
This makes them robust regarding truncation. Ideally, we'd export this as an API, but given how messy SIGBUS handling is, and the uncertain ownership logic of signal handlers we should not do this (unless libc one day invents a scheme how to sanely install SIGBUS handlers for specific memory areas only). However, for now we can still make all our own tools robust. Note that external tools will only have read-access to the journal anyway, where SIGBUS is much more unlikely, given that only writes are subject to disk full problems.
