textproc/clucene: apply gentoo patch for C++17 conformance
Some parts of CLucene use std::binary_function, which was deprecated in
C++11, and has been completely removed as of C++17. This shows up while
building libreoffice with clang >= 16 or gcc >= 11, because C++17 is the
default standard now.
Apply a diff from https://bugs.gentoo.org/869170 that fixes this, by
removing usage of std::binary_function, and replacing it with typedefs.
