Check your /usr/lib/systemd/system/lircd.service.  It may have been
over-written by the update.  Make a copy in /etc/systemd/system and
modify the copy.  Mine now looks like this:

# cat /etc/systemd/system/lircd.service 
[Unit]
Description=LIRC Infrared Signal Decoder
After=network.target

[Service]
Type=simple
EnvironmentFile=-/etc/sysconfig/lirc
ExecStartPre=/sbin/modprobe -qa lirc_zilog
ExecStartPre=-/bin/sh -c 'test -n "${LIRCD_IR_DEVICE}" && \
    echo lirc > /sys/class/rc/${LIRCD_IR_DEVICE}/protocols || :'
ExecStart=/bin/sh -c '/usr/sbin/lircd ${LIRCD_OPTIONS} \
    --driver ${LIRC_DRIVER} --device ${LIRC_DEVICE}  --nodaemon'
ExecStopPost=-/bin/sh -c 'test -n "${LIRCD_IR_DEVICE}" && \
    echo -lirc > /sys/class/rc/${LIRCD_IR_DEVICE}/protocols || :'
