editorconfig: fix wildcard expansion

It turns out that wildcard expansion, * and ?, is not performed in
matching lists {...}, at least in the vim plugin. The spec is not clear
about that, but refer to "pattern matching through Unix shell-style
wildcards" [0].

So, let's consider that this is not supported. Expand the patterns into
one section each, rather than use a list.
