Subject: [PATCH] perf: make util/data.h self-contained

struct perf_data in util/data.h uses "u64" data type, which is defined in
"linux/types.h". If only include util/data.h, following compilation error
occur:

util/data.h:38:3: error: unknown type name ‘u64’
   u64    version;
   ^~~

Solution: include "linux/types.h." to resolve self-contained issues

Fixes: 258031c017c35 (perf header: Add DIR_FORMAT feature to describe directory data)
