[OE-core] [PATCH 3/7] wic: Add wic-specific bootloader subclass

[Tom Zanussi]

Add a new wic-specific bootloader subclass so we can add a --source
param to hang non-partition plugin off of.

By default, the bootloader gets the /boot partition source plugin, but
this can be overridden by the --source bootloader param if needed.
