tiny-fugue: change to using HB pcre

tiny-fugue was crafted in 2007 to use pcre, and it uses system
pcre or HB pcre over its own internal pcre-2.08 by linking against
`-lpcre`. However it uses a removed API, `pcre_info` like goffice
tries to do.

- Add a dep on HB pcre.
- patch this to change to using `pcre_fullinfo`
- design the patch like the goffice patch.

Fixes #15105

Closes #15681.
