wm4 6d6ae638fa lirc: silence output in case LIRC can't be opened
By default mplayer attempts to use LIRC. If LIRC can't be opened, a
bunch of warnings are printed. Since mplayer is often built with LIRC
enabled by default, many users will see these rather pointless
warnings. Lower verbosity, so that the warnings are not visible by
default anymore.
