Walter Erquinigo 2098e2f472 [trace][intel pt][simple] Fix errors after switching to libipt's top of tree
These tests were being tested against a version of libipt from last
year. We just updated libipt to top of tree and many errors broke
because the new version of libipt emits more events than the older one,
which is fine.

`./bin/lldb-dotest -p TestTrace` passes
