ARM: at91: sama5_defconfig: add back CONFIG_JUMP_LABEL

Add back this configuration option as it increases a lot the performance
of the network subsystem.
Beware: this option changes the binary of the kernel at runtime: pay attention
if you use the Integrity Check Monitor (ICM) with the kernel image!
