base-files: nand: use CI_KERNPART whenever the kernel volume is needed

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
This patch is in continuation of: commit 93aa86040523
"procd: nand: make it possible to configure kernel and ubi partition"

The $CI_KERNPART variable should be used in place
of the fixed "kernel" partition name. This allows
targets to specifiy alternate names for the kernel
partition.
