config: Improve _Configure_From_workspace()

Commit 4c09f4b3fefc7ba5c5868a97ad00c1ee14a06677 changed the cast from
size_t to ssize_t to try to fix an workspace issue on 16-bit
architectures.  This change was reverted by commit
7ff6115b8b913d848b8fe76daf72ca0b4bbf2548 for the workspace but not
_Configure_From_workspace().  Change the cast to uintptr_t to be in line
with the Heap Handler.
