kernel: fix broken initramfs images for Separate cpio

Browse Source 
Commit 0137fbd74b ("kernel: skip rebuilding kernel with
ROOTFS_INITRAMFS_SEPARATE") had a logic error error and didn't account
that the generic initramfs is still needed to be built to enable support
for the cpio compression and other config specific to initramfs. With
that commit we completely skip rebuilding the kernel with those new
options.

To better handle this, skip kernel build ONLY when we are handling Per
Device Rootfs, permitting the first generic build to be actually called
with the new options.
