libssh2: allocate libssh2-friendly memory in kbd_callback

The function libssh2_userauth_keyboard_interactive_ex() calls the
callback and is documented to call free() on the memory returned to
libssh2 from the callback. libcurl can therefore not use the regular
curlx_strdup() for this, as that is not compatible in debug builds when
curl_global_init_mem() is used.

Fixes #21336
