Jiri Olsa 29245ae8ff perf tools: Do not swap mmap2 fields in case it contains build id

If the PERF_RECORD_MISC_MMAP_BUILD_ID misc bit is set, mmap2 events
carries a build id, placed in the following union:

  union {
          struct {
                  u32       maj;
                  u32       min;
                  u64       ino;
                  u64       ino_generation;
          };
          struct {
                  u8        build_id_size;
                  u8        __reserved_1;
                  u16       __reserved_2;
                  u8        build_id[20];
          };
  };

In this case we can't swap above fields.
