git: enable perl (broken); add CA certificate bundle

- Enables Perl support for GIT. Fake Provides: records were
  added to SPEC file to hide installaiton errors. Requires
  perl dependencies are not available on the system. The hack
  should allows git add --interactive to work.
- Add Certification Authority certificates, which are not available
  on Darwin platform.
