Dali dataPath incorrectly used unless specified with trailing path separator

NB: observed in containerized setup's.

If the dataPath directory in Dali's config file does not have a trailing path separator (which is the case in a default container setup), then some of Dali's files are written to the wrong place, e.g. with dataPath: "/var/lib/HPCCSystems/dalistore",
some files, like the store.<nnn> file are being written to "/var/lib/HPCCSystems/dalistorestore.<nnn>"
