Use fixed version of curl in quic-interop-container

As part of 6aaac9dd388a64d0f511544496608693e1105d13 in
https://github.com/curl/curl.git

Curl dropped support for using the quic-tls interface to use our quic
stack.  Because our interop testing relies on using curl to do testing,
our builds broke.

Until we can find an alternate client to do https transfers over
http3/quic, we need to back off our quic build point to a commit prior
to the above so we can maintain our interop testing.

Long term, we need to enhance our own http3 demo client to support the
download/resumption/etc features that we need for interop.  We're
tracking that effort in:
https://github.com/openssl/project/issues/1850

Fixes openssl/project#1848
