Super simple test to check that at least we're not segfaulting when
trying to use 'perf report --hierarchy', more subtests should be added
to make sure the output is the expected one.
This is being merged right before a fix for that that this test detects:
# perf test hierarchy
83: perf report --hierarchy : FAILED!
# perf test -v hierarchy
--- start ---
test child forked, pid 102242
perf report --hierarchy
