subrepoutil: use relative path for looking up config `%include`s

The code was already working with relative paths in practice, since it
passed in a (repo-)relative path into its local `read()` function. So
all that this patch actually does is to switch to rename variables so
we use the same path by a different name. This gets us closer to
removing the "absolute" path from the `include` callback.
