perf tools: Start the perf.data mapping at data offset in perf trace
Currently, we are mapping perf.data in the beginning of the file
and use the data offset as a buffer offset.
This may exceed the mapping area if the data offset is upper than
page_size * mmap_window and result in a page fault (thing that
happen if we merge trace.info in perf.data).
Instead, let's start the mapping in the page that matches our data
offset.
v2: Drop a junk from another patch (trace_report() removal)
