utils/genrandconfig: rework fine-tuning logic

Browse Source 
Before calling randpackageconfig/randconfig, we were pre-generating a
snippet of .config with:

 (1) minimal.config
 (2) BR2_CURL/BR2_WGET settings
 (3) some random selection of init system, debug, runtime debug, etc
 (4) enabling BR2_REPRODUCIBLE=y when diffoscope was found

Now that we only use randconfig, this whole fine-tuning is completely
irrelevant, as it gets overridden by "make randconfig".

(1) and (3) above are useless, as randconfig does all the
randomization that is needed.

However, we want to preserve (2) and (4) above, so we re-implement
those fixups, but *after* randconfig has done its job.
