Hi.

Following simple patch introduces support for a local DSO lookup operation.
Motivation is that if I have a perf.data file which is created on a different
machine (perf record $very_long_path), using perf report with --symfs=$workdir
expects a DSO to be located at: $workdir/$very_long_path.

I think it would be much easier to copy a binary file to the $workdir and
let perf lookup the working directory: $workdir/binary_filename.

Thanks,
Martin
