[OE-core] [PATCH 1/2] classes/populate_sdk_base: don't break existing do_populate_sdk depends

[Paul Eggleton]

We set do_populate_sdk[depends] in populate_sdk_*.bbclass, but since
these are inherited at the top of populate_sdk_base.bbclass, those
values are wiped out by using = at the end of the latter class. Use +=
to avoid this.
