selftests/ftrace: Update synthetic event syntax errors
[ Upstream commit b5734e997e1117afb479ffda500e36fa91aea3e8 ]
Some of the synthetic event errors and positions have changed in the
code - update those and add several more tests.
Also add a runtime check to ensure that the kernel supports dynamic
strings in synthetic events, which these tests require.
