kernel: mtdsplit: calculate kernel partition precisely for Seama

Browse Source 
So far "kernel" partition didn't contain just a kernel. It also included
Seama header and meta data. This was making kernel update complex and it
wasn't trivial to read kernel size.
Fix it by making "kernel" parition contain just a kernel image.
