Stephane Eranian ac5e7f84c0 perf symbols: Fix bug in usage of the basename() function 
The basename() implementation varies a lot between systems.

The Linux man page says: "basename may modify the content of the path,
so it may be desirable to pass a copy when calling the function".

On some other systems, the returned address may come from an internal
buffer which can be reused in subsequent calls, thus the results should
also be copied.

The dso__set_basename() function was not doing this causing problems
on some systems with wrong library names being shown by perf report,
such as on Android systems.

This patch fixes the problem.
The patch is relative to tip.git.

In v2, we clean up the comments based on Ingo's feedback.
