Testing PFX file breaks with latest vendored openssl

@trinity-1686a says, on !132 (merged):

note: nightly CI is failing because vendored/bundled openssl does not support "RC2-40-CBC". Sounds old and deprecated. Shall I try to create a new .pfx with newer crypto, or downgrade openssl-src back to something that support RC2?

We should indeed replace this pfx file.

Please let me know here if you get stuck, @trinity-1686a, and I can try to figure it out? I think that passing the -aes128 flag to the openssl pkcs12 command might be enough. (The instructions are in a comment in crates/tor-rtcompat/src/test.rs.)
