Configs: Everest: update names of leds directly connected to BMC

There are 4 leds that are directly connected to BMC's gpio bank.
Existing group config represented them as:
 - rear_enc_id0
 - rear_enc_fault0
 - bmc
 - rtc_battery

However, openbmc/docs/designs/device-tree-gpio-naming.md says
that they have prefix led-. Hence, it is updated to:
 - led_rear_enc_id0
 - led_rear_enc_fault0
 - led_bmc
 - led_rtc_battery
