perf tools: Implement addr2line directly using libbfd

When the srcline sort key is used , the external addr2line utility needs
to be run for each hist entry to get the srcline info.  This can consume
quite a time if one has a huge perf.data file.

So rather than executing the external utility, implement it internally
and just call it.  We can do it since we've linked with libbfd already.
