payload: Fix broken Linux kernel as payload

Commit 785a31d67e8f34065a2483080e4fd7032c3a8aad
( Move payload code to payloads/) breaks the usage of
Linux kernel as payload. The reason for it is that cbfs-files-y is
evaluated before payloads/external/ is sourced and as a
consequence ADDITIONAL_PAYLOAD_CONFIG is empty when it is used for
payload options. That leads to missing command line and initrd for
the kernel which in turn leads to kernel panic when it boots.
To avoid it, move the code which adds payload to cbfs completely to
payloads/extranal/ This way, ADDITIONAL_PAYLOAD_CONFIG is
set right before the payload itself is added to cbfs-files-y.

I have tested this patch with a Linux kernel as well as with SeaBIOS as
payload on mc_tcu3 and it works. If someone sees impact to other
payloads just let me know.
