gitweb: Use Git credential helper when cloning URLs with credentials
This prevents logging usernames and passwords to the journal logs and to the
Git repo configuration. Also, avoids usernames and passwords appear in the
process list when cloning a repository.

Tests performed:
- Create a new repository by cloning an existing repository URL with basic
auth credentials. Check that:
  - Cloning succeeds.
  - Journal logs don't contain URLs with credential info.
  - The configuration of the cloned repository doesn't contain credential info.
- Try to clone a non-existing repository URL that contains credential
info. Cloning fails and there are no credential info in the journal logs.
- Cloning a public git repository without credential info succeeds.
- All the gitweb module tests pass.
