perf lock contention: Show lock type with address

Browse source

Show lock type names after the symbol of locks if any.  This can be
useful especially when it doesn't show the lock symbols.

The indentation before the lock type parenthesis is to recognize lock
symbols more easily.

  $ sudo ./perf lock con -abl -- sleep 1
   contended   total wait     max wait     avg wait            address   symbol
