loplugin:redundantcast (size_t vs. std::size_t)

...which happen to be found by 6efffbbfce9c27439f54970f7a569b069ce46eba "Improve
loplugin:redundantcast for sal_Int... vs. ::sal_Int..." only on macOS, not on
Linux:  At least for my Linux builds, size_t is a typedef in my local LLVM
installation's lib/clang/11.0.0/include/stddef.h while std::size_t is an
unrelated typedef (but to the same type) in
/usr/include/c++/9/x86_64-redhat-linux/bits/c++config.h.
