Pin the kernel and initrd the riscv64 live image carries, that the kernel name
the other live images use is not accepted for it, and that the architecture the
media reports maps to riscv64 in both directions.

Build each Ubuntu media layout on disk and ask the resolver for its kernel and
initrd: the netboot trees, the flat netboot layout, both casper images, and the
POWER layouts where the kernel and the initrd sit in different directories.
Pin the precedence the installer depends on, a netboot tree over a live image
and a hardware-enablement kernel over the release one, and pin the three ways
media resolve to nothing.
