ca-certificates: Update to work with python3 version of certdata2pem.py

- Implement python3 version of certdata2pem.py script from fedora
- Modify build.sh to work with python3 script that uses p11-kit based on fedora
   approach - https://src.fedoraproject.org/rpms/ca-certificates/tree/rawhide
- Extraction of cert files now uses p11-kit which requires libtasn1 as a build
   dependency
- Updated rootfile
- Updated ca-certificates installed into a vm and confirmed to download a file from an
   https site with the same results as with existing ca-certfictaes system
