classes/kernel: fix symlink logic when bundling initramfs images 

If linkpath points to the a file in KERNEL_OUTPUT_DIR, rather than
outside, then symlink creation for the bundled initramfs image files
fails.

This is because in that case $linkpath.initramfs and $realpath.initramfs
are in the same directory, KERNEL_OUTPUT_DIR, and hence are the same.
Since we just created $realpath.initramfs, creating a symlink with the
same name will fail.

Given that $linkpath is not necessarily the same as the kernel image type,
just removing this symlink creation is not the right thing to do, as
in that case kernel_do_deploy() wouldn't find the bundled file.

What we really want is a symlink from the name of the initramfs-bundled
kernel image type to the real initramfs-bundled kernel image, as that is
what is actually used later in do_deploy().

This brings the code path for when $KERNEL_OUTPUT_DIR/$type is a symlink
in line with when it is not.
