DEPS handling: Use DEPS_INCLUDE everywhere

DEPS handling: Use DEPS_INCLUDE everywhere

DEPS_INCLUDE is currently the same as DEPS, so no functional change.

This patch is the result of this perl rune:

  git-grep -l 'include.*DEPS' | xargs perl -i -pe 'next unless m/^-?include/; s/\bDEPS\b/DEPS_INCLUDE/'

I have verified that I haven't missed anything, with this rune:

  git-grep '\bDEPS\b'
