build: parallelize repository readiness checks

[diegomarquezp]

Allows to run both scripts faster:

• clone_repositories: 30s
• check_status: 30s

Clone repositories was enhanced with sparse-checkout.

Be careful. Concurrency increases complexity.

clone_repositories.sh is needed only once.

I ran check_status.sh in this pull request, but it didn't seem to work.
