Patch: FYI: gcj-dbtool help output

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in.

This adds "--version" and "--help" to gcj-dbtool and cleans up the
help messages to have the correct program name.  Whether this is a
regression depends on your point of view; I think it falls into
"documentation fixes".
