.oniro-ci: find DEPLOY_DIR, not TMPDIR
Some jobs care about images and licenses, those look at the $TMPDIR/deploy, taking some effort to find the correct tmpdir while hard-coding the deploy dir. Take a shortcut and query for the right variable (DEPLOY_DIR).
This allows non-trivial layouts with DEPLOY_DIR and TMPDIR placed on distinct filesystems, for efficiency.
