Kernel: Don't allocate so much when generating coredumps

Instead of creating a bunch of ByteBuffers and concatenating them to
generate the "notes" segment, we now simply create a KBufferBuilder
and tell each of the notes generator helpers to write into the builder.

This allows the code to flow more naturally, with some bonus additional
error propagation. :^)
