support/testing/infra/basetest: support br2-external

Some upcoming test cases can use one or more br2-external trees as
fixtures that provide packages used only in runtime tests.

Add support for br2-external into the BRTest class. Any test case can
then provide a list of paths for being used as br2-external trees
during the build of the image to test.
