Apply overlays statically with fdtoverlay. This is a build time test that

the overlays can be applied successfully by fdtoverlay. This does not

guarantee that the overlays can be applied successfully at run time by

unittest, but it provides a bit of build time test coverage for those

who do not execute unittest.

The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to

create static_test_1.dtb and static_test_2.dtb. If fdtoverlay detects an

error than the kernel build will fail. static_test_1.dtb and

static_test_2.dtb are not consumed by unittest.

Some unittest overlays deliberately contain errors that unittest checks for.

These overlays will cause fdtoverlay to fail, and are thus not included

in the static test:
