REGTESTS: quic: ssl_curve_name.vtc supported by QUIC

ssl/ssl_curve_name.vtc was renamed to ssl/ssl_curve_name.vtci
to produce a common part runnable both for QUIC and TCP listeners.
Then ssl_curve_name.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);

Note that this script works by chance for QUIC because the curves
selection matches the default ones used by QUIC.
