Bump osbuilder to produce a livecd with tty1 as default console

Grub configuration for livecd (iso) is installed here:
https://github.com/kairos-io/osbuilder/blob/89b014b2b2a1f27bd0c0c5269cecec2a1b8f37bf/tools-image/Dockerfile#L25

and it repositories were bumped in osbuilder to use the latest and
updates grub configuration where `console=tty1` is set **after**
`console=ttyS0` thus making it the default console for systemd services.

Also:

- remove not used bootargs.cfg file (has been moved to the "packages"
  repo)
- Change to the DATASOURCE check which is what we need in reality (not
  CLOUD_INIT which was indirectly checking that DATASOURCE would be set
  by Earthly)
