doc/Makefile: Added all asciidoc files to EXTRA_DIST and clean up all doc.
tools: Log library versions as well on startup.
integration tests: Use LD_PRELOAD only when running SysDB tools.

Just as a cleanup.

valgrind does not play well with the address sanitizer. Also, there's no need
to rerun the regular tests on asan generated code (which is a test on its
own).
