disable multiplexing for some versions of curl 

I'm behind a corporate proxy and was hitting a `Curl 2 (...) [CONN-1-0] send: no filter connected` error when trying to download some packages.

Some google research led me to https://github.com/rust-lang/cargo/issues/12202 and its fix https://github.com/rust-lang/cargo/pull/12234.

This PR backports this fix to composer.

> In certain versions of libcurl when proxy is in use with HTTP/2
multiplexing, connections will continue stacking up. This was
fixed in libcurl 8.0.0 in curl/curl@821f6e2
