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.
