perf tools: Fix command line filters in hierarchy mode

When a command-line filter is applied in hierarchy mode, output is
broken especially when filtering on lower level.  The higher level
entries doesn't show up so it's hard to see the results.

Also it needs to handle multi sort keys in a single hierarchy level.

Before:

  $ perf report --hierarchy -s 'cpu,{dso,comm}' --comms swapper --stdio
  ...
  #    Overhead  CPU / Shared Object+Command

         11.89%     [kernel.vmlinux]  swapper
          9.18%     [kernel.vmlinux]  swapper
