liveinstall: Use kernel-uki-dtbloader kernel on aarch64

For aarch64 liveinstall images we want to replace the kernel-core package
with kernel-uki-dtbloader for:

https://fedoraproject.org/wiki/Changes/Automatic_DTB_selection_for_aarch64_EFI_systems

This is implemented by:

1. Adding a new BootCoreLive profile which is the same as the BootCore
profile and re-uses most of the description. Rreplacing the kernel-core
package with kernel-uki-dtbloader on aarch64.

2. Switch the LiveInstall from the BootCore profile to the BootCoreLive
profile.
