perf list: Also append PMU name in verbose mode

When listing in verbose mode, the long description is used but the PMU
name isn't appended. There doesn't seem to be a reason to exclude it
when asking for more information, so use the same print block for both
long and short descriptions.

Before:
  $ perf list -v
  ...
  inst_retired
       [Instruction architecturally executed]

After:
  $ perf list -v
  ...
   inst_retired
       [Instruction architecturally executed. Unit: armv8_cortex_a57]
