libunit-wasm: Allow to set the HTTP response status

This adds a new luw_http_set_response_status() function that takes one
of the luw_http_status_t response status codes.

This function should be called before any calls to
luw_http_send_headers() or luw_http_send_response().

This function calls into Unit via a new function import,
nxt_wasm_set_resp_status().
