[PATCH] kbuild: Rename Makefile.extrawarn to Makefile.warn

[PATCH] kbuild: Rename Makefile.extrawarn to Makefile.warn

[Nathan Chancellor]

Since commit e88ca24319e4 ("kbuild: consolidate warning flags in
scripts/Makefile.extrawarn"), scripts/Makefile.extrawarn contains all
warnings for the main kernel build, not just warnings enabled by the
values for W=. Rename it to scripts/Makefile.warn to make it clearer
that this Makefile is where all Kbuild warning handling should exist.
