dynapi: order for a reproducible build

Browse Source 
The objfiles of different builds show various differences in
the calls to SDL_DYNAPI_entry elements. This is generated
dynamically by gendynapi.pl which uses an unordered opendir/readdir
pair. To make the build reproducible and thereby e.g. debugging
easier change this to be used in an ordered fashion.

Fixes #11565.
