serializer: define order of including files in includedir

In the reference documentation <includedir> has an undefined
order of including files from a directory.

This makes the order unoficially and implicitly defined to make
generated serialized files equal for the same set of files.
It does not mean that users may now rely on it.

The order is alphabetical.
