Patch NSS build to get rid of unused libc networking symbols
In #40093 (closed) we removed the unneeded libc networking symbols to make sure no Rust code is bypassing our proxy requirement. It turns out, though, that this nice workaround is brittle due to compiler constraints. Thus, we should right from the beginning (that is in NSS build land) avoid the inclusion of those symbols (instead of getting rid of them later on with the help of LTO).
