perf evsel: Fix inverted test for fixing up attr.inherit flag
The kernel refuses mmapping an event with the inherit flag set for
something that is systemwide (cpu == -1), and the evsel layer got this
reversed at some point, fix it.
The symtom was that the --pid and --tid parameters for 'perf record' and
'perf top' returned with -EINVAL, like:
# /tmp/build-perf/perf record -v -fo/tmp/perf.data -p 1042
Warning: ... trying to fall back to cpu-clock-ticks
Fatal: failed to mmap with 22 (Invalid argument)
