narrowspec: use sparse.parseconfig() to parse narrowspec file (BC)

This also make narrow files use 'include' and 'exclude' instead of plural forms
which are 'includes' and 'excludes'.

This is BC because existing narrowspecs have to replace excludes, includes words
with exclude and include i.e. their singular versions.
