Rollup merge of rust-lang#38164 - sourcefrog:fonts, r=GuillaumeGomez

Avoid using locally installed Source Code Pro font (fixes rust-lang#24355).

In some versions of this font the ampersands are drawn badly.

A doc tree built with this change is at https://storage.googleapis.com/mbp-rust-builds/fonts/doc/std/index.html

I'm not seeing this problem locally so I'm not sure this fixes it, but based on the diagnosis in the bug it should.

I've made this a minimal change by only removing the one problematic font but maybe for consistency every font should be read from the Rust docs tree?
