add missing dependency for ipopt on libscotch

[minrk]

See conda-forge/ipopt-feedstock#112 (comment)

ipopt linked libscotch as a transitive dependency of mumps without declaring it as a dependency, meaning a mumps rebuild against an updated libscotch would break ipopt, which happened with mumps 5.7.3 build 5.

Since mumps pins libscotch all the way down, the only builds for which this is a problem is when a given version of mumps bumps libscotch after ipopt has been built against that mumps.

Since tracking down the scotch at build time for each ipopt build is tedious and the transitive pin from mumps is ~always right for past builds, only apply this patch to the latest version of ipopt (3.14.16).

All builds against mumps 5.6-5.7.2 only have builds against scotch 7.0.4, and only ipopt 3.14.16 has builds against 5.7.3. So while this added dependency is correct, it's only strictly needed to solve a problem for ipopt 3.14.16 build number 5, the first build against mumps 5.7.3.
