GitLab: Fix nolib build directories

The Gaea GitLab test configuration includes two no-library compilation
tests for ocean-only and ice-ocean configurations.  They are currently
configured to run in the same directory.

Recently, several unusual I/O errors suggest problems due to concurrent
testing of the builds.  In order to rule out this possibility, this
patch moves the ice-ocean test to a separate directory.
