configs: Enable EL3 in the arm-ubuntu-boot-exit example

Browse Source 
EL3 (SECURITY) had been temporarily disabled to address the
FEAT_PAuth trapping issue.

This was caused by the EL3 bootloader not disabling pointer
authentication traps. Now that this has been implemented [1],
we should re-enable EL3 in this example platform
