[PATCH 18/25] perf evsel: Remove needless stddef.h from util/evsel.h

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

We added it in 07ac002f2fcc ("perf evsel: Introduce is_group_member
method") but we already ditched that function, and there was nothing
else left that needed NULL nor anything else from stddef.h, ditch it.
