[PATCH] perf tools: Replace zero-length array with flexible-array member

From: cgel . zte

From: Changcheng Deng <deng.changcheng@xxxxxxxxxx>

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use "flexible array members" for these cases. The older
style of one-element or zero-length arrays should no longer be used.
