scripts: correctly warn when the local tarballs directory does not exist
Warn about a missing local tarball directory, only if it was configured.
Avoid the spurious message:
Directory '${CT_LOCAL_TARBALLS_DIR}' does not exist.
Will not save downloaded tarballs to local storage.
Thanks to "Pedro I. Sanchez" <psanchez@colcan.ca> for pointing out the
issue:
