Subject: perf tools: Add missing forward declaration of struct map to probe-event.h

From: Wang Nan <wangnan0@huawei.com>

commit 5a023b57a8e96327925a39312bccc443a7c540b6 upstream.

Commit 7b6ff0bdbf4f7f429c2116cca92a6d171217449e ("perf probe ppc64le:
Fixup function entry if using kallsyms lookup") adds 'struct map' into
probe-event.h but not forward declares it. This patch fixes it.
