media: rc: lirc does not use LIRC_CAN_SEND_SCANCODE feature

Since commit 02d742f4b209 ("media: lirc: lirc daemon fails to detect raw IR device"), the feature LIRC_CAN_SEND_SCANCODE is no longer used as it tripped up lircd. The ability to send scancodes for IR Tx is implied by LIRC_CAN_SEND_PULSE (i.e. any device that can send can use IR Tx encoders).

So, remove LIRC_CAN_SEND_SCANCODE since it never used. This fixes:
