[PATCH 36/66] libperf: Add missing 'struct xyarray' forward declaration

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

We were getting it by luck, from files included before internal/evsel.h
where it is being included.

Fixes: 9dfcb7599084 ("libperf: Move fd array from perf's evsel to lobperf's perf_evsel class")
