As tests are now part of OCL repository, we prefer to always
run tests from local repository version on the same version
of OCL, so instead of cloning OCL from GitHub we just copy
local repository to DUT.
This also simplifies running remote tests in development
environment without need to push work-in-progress commits
to GitHub or installing OCL manually on DUT.
