[PATCH] perf parse-events: Set exclude_guest for user-space counting

Currently if we run 'perf record -e cycles:u', exclude_guest is 0.

But it doesn't make sense that we request for user-space counting
but we also get the guest report.

To keep perf semantics consistent and clear, this patch sets
exclude_guest for user-space counting.
