init-install-efi.sh: Update to support installing multiple kernels

We can no longer rely on the kernel having a static name of "vmlinuz".
This means we can't use it as a sentinel value in our sed commands, and
we can't just copy vmlinuz to the boot directory.

Instead, we'll use "root=" as the sentinel value for our sed commands,
and we'll search for common kernel names to copy into our boot
directory.
