perf intel-pt: Fix syntax in documentation of config option

Browse Source 
As specified in tools/perf/Documentation/perf-config.txt, perf
configuration items must be in 'key = value' format, otherwise the
following error message occurs:

  $ perf record -e intel_pt//u -- ls
  bad config file line 2 in ~/.perfconfig
  $ cat .perfconfig
  [intel-pt]
      mispred-all

Changing to assigning a value to the key 'mispred-all' fixes the issue:

  $ perf record -e intel_pt//u -- ls
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Capured and wrote 0.031 MB perf.data]
  $ cat .perfconfig
  [intel-pt]
      mispred-all = true
