Leo Yan aa616f5a8a perf jit: Let convert_timestamp() to be backwards-compatible 
Commit d110162caf ("perf tsc: Support cap_user_time_short for
event TIME_CONV") supports the extended parameters for event TIME_CONV,
but it broke the backwards compatibility, so any perf data file with old
event format fails to convert timestamp.

This patch introduces a helper event_contains() to check if an event
contains a specific member or not.  For the backwards-compatibility, if
the event size confirms the extended parameters are supported in the
event TIME_CONV, then copies these parameters.

Committer notes:

To make this compiler backwards compatible add this patch:

  -       struct perf_tsc_conversion tc = { 0 };
  +       struct perf_tsc_conversion tc = { .time_shift = 0, };

Fixes: d110162caf ("perf tsc: Support cap_user_time_short for event TIME_CONV")
