perf tools: Improve message about missing symtabs for deleted DSOs

Instead of:

  no symbols found in /usr/lib/gstreamer-0.10/libgsttypefindfunctions.so (deleted), maybe install a debug package?
  no symbols found in /usr/lib/gstreamer-0.10/libgstaudioconvert.so (deleted), maybe install a debug package?

We now emit:

  /usr/lib/gstreamer-0.10/libgsttypefindfunctions.so was updated, restart the long running apps that use it!
  /usr/lib/gstreamer-0.10/libgstaudioconvert.so was updated, restart the long running apps that use it!

Which is far less misleading about what the cause of the
symbol mismatch is.
