T7530: Build package binaries script should exit if repo is absent

The build package binaries script should exit if the repo is absent
or cannot be cloned

If a build package `repo-a` depends on the `repo-b` and the `repo-b`
cannot be cloned, then we shoud exit from the script to avoid
partly build dependencies

For example:
```
[[packages]]
name = "fake-repo"
commit_id = "v0.0.1"
scm_url = "https://github.com/vyos/fake-repo"

[[packages]]
name = "ethtool"
commit_id = "debian/1%6.10-1"
scm_url = "https://salsa.debian.org/kernel-team/ethtool"
```

If ethtool depends on some fake-package and this package cannot be
downloaded from the repo, then we shouldn't build the ethtool package
at all.
