perf script python: Add Python3 support to tests/attr.py

Browse Source 
Support both Python 2 and Python 3 in tests/attr.py

The use of "except as" syntax implies the minimum supported Python2 version is
now v2.6

Committer testing:

  $ make -C tools/perf PYTHON3=python install-bin

Before:

  # perf test attr
  16: Setup struct perf_event_attr                          : FAILED!
  48: Synthesize attr update                                : Ok
  [root@quaco ~]# perf test -v attr
  16: Setup struct perf_event_attr                          :
  --- start ---
  test child forked, pid 3121
    File "/home/acme/libexec/perf-core/tests/attr.py", line 324
      except Unsup, obj:
                ^
  SyntaxError: invalid syntax
  test child finished with -1
  ---- end ----
  Setup struct perf_event_attr: FAILED!
  48: Synthesize attr update                                :
  --- start ---
  test child forked, pid 3124
  test child finished with 0
  ---- end ----
  Synthesize attr update: Ok
  #

After:

   # perf test attr
  16: Setup struct perf_event_attr                          : Ok
  48: Synthesize attr update                                : Ok
