MINOR: hlua: Remove useless test on TX_CON_WANT_* flags

When an HTTP applet is initialized, it is useless to force server-close mode on
the HTTP transaction because the connection mode is now handled by muxes. In
HTX, during analysis, the flag TX_CON_WANT_CLO is set by default in
htx_wait_for_request(), and TX_CON_WANT_SCL is never tested anywere.
