payloads: Reorganize Kconfig for external payloads

The integration of external payloads in coreboot
is a bit messy. You have to change the to level Kconfig
file for every payload (something that we recently fixed
for mainboards and chipsets). This means that updating
e.g. the SeaBIOS version requires a change outside of the
SeaBIOS directory.

With this patch you can create a new directory under
payloads/external and place a Kconfig and Kconfig.name
file in there, and the payload will automatically show
up when you do "make menuconfig".
