New define USE_SO_NOSIGPIPE in curl_setup.h, for now set whenever SO_NOSIGPIPE is defined. Maybe overridden in the future on systems where this does not work. With USE_SO_NOSIGPIPE defined, set SO_NOSIGPIPE on all sockets created by libcurl and fail the creation when setsockopt() fails. Closes #20370
