kbuild: redo fake deps at include/config/*.h
Make include/config/foo/bar.h fake deps files generation simpler.
* delete .h suffix
those aren't header files, shorten filenames,
* delete tolower()
Linux filesystems can deal with both upper and lowercase
filenames very well,
* put everything in 1 directory
Presumably 'mkdir -p' split is from dark times when filesystems
handled huge directories badly, disks were round adding to
seek times.
x86_64 allmodconfig lists 12364 files in include/config.
