fix(FreeBSD): Installation fix

- Removed `--skip-unresolvable` incorrect option to pkg
- Install and setup nvidia drivers during pkg setup
- Do NOT install kitty by downloading binary for FreeBSD
- Add more packages for installation through pkg in FreeBSD
- WIP: Some required packages could not be installed in FreeBSD because
  they have longer names. Those package names are stored at the end of
  the package-list-os file for now.
