[PATCH v1 06/49] perf python: Clean up pylint warnings in twatch.py

[Ian Rogers]

Clean up pylint warnings in twatch.py so that it passes pylint without
warning suppression comments:
- Convert tab indentation to 4 spaces (W0311: bad-indentation).
- Remove unnecessary trailing semicolon (W0301: unnecessary-semicolon)
  after evsel.open().
- Convert floating multi-line string comments to '#' comments (W0105:
  pointless-string-statement).
