fill "show cpu" Flag list on aarch64 platforms (VPP-1065)

use getauxval(AT_HWCAP) to get the processor capabilities. The result should be the same as calling cat /proc/cpuinfo | grep Feature | head -n1 All but one (aes) features have a different name. handle aes by adding it an arch prefix, which is skipped during print and a clib_cpu_supports_aes() custom function.
