update checkpatch.pl to version 0.13

This version brings a large number of fixes which have built up over
the Christmas period.  Mostly these are fixes for false positives, both
through improvments to unary checks and possible type detection.  It
also brings new checks for while location and CVS keywords.  Of note:

  - a number of fixes to unary detection
  - detection of a number of new forms of types to improve type matching
  - better inline handling
  - recognision of '%' as an operator

      Version: 0.13
      unary detection: maintain bracket state across lines
      move to pre-sanitising the entire file
