kbuild: Removed unused definitions

o Deleted subdir-n and subdir- handling in Makefile.build
o Deleted all host-progs related stuff in Makfile.modver
o In Makefile.modver also deleted everything related to composite objects
o Fixed an error when deleting a .ver file + .hdepend and then do make
  - filter-out in Makefile.modver was faulty
