release 2.10.3 2025-11-21

Define `__GNU_VISIBLE` in `soup/walk.h` before it includes `<fnmatch.h>`
in an effort to help Cygwin compile the code.  Reports were that
`FNM_CASEFOLD` was undefined for some Cygwin users.

Changed `MKIOCCCENTRY_REPO_VERSION` to "2.10.3 2025-11-21".
Changed `SOUP_VERSION` to "2.3.3 2025-11-21",

Ran `make release` to test the above.
