IMPALA-9545 Decide cacheline size of aarch64

ARM64's L3 cacheline size is different according
 to CPU vendor's architecture. If user defined
 CACHELINESIZE_AARCH64 in impala-config-local.sh,
then we will use that value, if user did not
 define it, then we will get the value from OS,
if fail, then we will use the default value 64.
