Fix early-cycle analysis switch (#1705)

By default, the early-cycle EnKF is designed to write analysis files. The switch controlling this was using `$CDUMP` which was changed by PR #1421. This current PR updates this switch to use `$RUN` in accordance with issue #1299, and restores the default analysis file write capability.
