PATCH 1/1 tracing/pt_test.c: Fix compiler errors on old distros

Compilation fails on old distros which don't have linux/perf_event.h and LTP_CHECK_PERF_EVENT can check the existence of linux/perf_event.h as well, so we just include perf_event.h header file when HAVE_STRUCT_PERF_EVENT_MMAP_PAGE_AUX_HEAD is defined.
