mail/thunderbird: fix build with clang 19

Browse Source 
clang/libcxx 19 is more strict about std::char_traits, causing build
failure in the rnp submodule. Import patches from upstream (rnp).

In clang/libcxx 19, treatment of std::char_traits was tightened
down - e.g. no generic (std::char_traits<unsigned char> etc) traits
are not implemented anymore - which resulted in fallout in HEAD
after the import of llvm/libcxx 19.
jkim@ collected the neccessary patches from
https://github.com/rnpgp/rnp/commit/20419f739f632fb30666650544f0055e8d4f1afa
