anaconda: switch container-installer to fixed ks

Use a fixed kickstart to cut corners, this needs a PoC as soon as
possible.

We need manual partitioning because we need to set the boot label on the
`/boot` partition. It is possible that this won't be necessary in the
future: rhinstaller/anaconda#5363

We'll remove the kickstart literal once the PR is merged and the options
used are merged into the kickstart stage.
