kbuild,gcov: remove unnecessary workaround

Since commit 371fdc77af (kbuild: collect shorthands into
scripts/Kbuild.include), scripts/Makefile.clean includes
scripts/Kbuild.include.

The workaround and the comment block in kernel/gcov/Makefile
are no longer necessary.

# not defined during clean or to include Kbuild.include in
