Add a 'ptr' field to fdarray->priv array.
This feature will be used by following commits, which introduce muiltiple 'struct perf_mmap' array for different types of mapping. Because of this, during fdarray__filter(), a simple 'idx' is not enough. Add a pointer cookie allows directly associate a 'struct perf_mmap' pointer to an fdarray entry.
