REGTESTS: quic: ssl_sni_auto.vtc code provision for QUIC

ssl/ssl_sni_auto.vtc was renamed to ssl/ssl_sni_auto.vtci
to produce a common part runnable both for QUIC and TCP listeners.
Then ssl_sni_auto.vtc files were created both under ssl and quic directories
to call this .vtci file with correct VTC_SOCK_TYPE environment values
("quic" for QUIC listeners and "stream" for TCP listeners);

Mark the test as broken for QUIC
