ci: enable linuxquic in interop tests

Build and install the Linux QUIC module in CI interop tests when
either the client or server is Linux QUIC, ensuring its availability
in interop CI.

Note if the kernel already supports QUIC (the uapi header file
/usr/include/linux/quic.h exists), it will not clone and build the
Linux QUIC module from lxin/quic repo.
