Currently, randconfig is completely unusable. Instead, we use randpackageconfig, with two use cases: in the autobuilders, and when doing manual testing of the validity of depends/select chains. In both cases, we actually want the possibility to explicitly select some packages or to set a string value or to randomise between a choice or to test bootloaders and kernels - all of this is currently impossible. With this patch, we can use randconfig instead of randpackageconfig, and provide it with a seed file specified with BR2_RAND_PRESEED_CONFIG.
