nscd: Improve nscd.conf comments.
This change adds a warning to nscd.conf about running multiple caching
services together and that it may lead to unexpected behaviours. Also we
add a note that enabling the 'shared' option will cause cache hit rates
to be misreported (a side effect of the implementation).

- Rewrite comment to avoid implementation details.
