simpleperf: enforce support of dwarf based callgraph. If it is not supported by the kernel, it may be because a kernel patch "perf: Fix arch_perf_out_copy_user default", or a configuration HAVE_PERF_USER_STACK_DUMP is missing. Bug: http://b/63634097 Test: run simpleperf_unit_tests. Change-Id: I4d3b2de72925c3566bcb0ebe41872919b7312687
