[contrib] validate_failures.py: fix python 3.12 escape sequence warnings

Adapt GCC's commit 90becd94cf92858555e0e538ec2091f952971453 to avoid
warnings such as:

validate_failures.py:68: SyntaxWarning: invalid escape sequence '\s'
  _INTERESTING_RESULTS_REX = re.compile('(%s):\s*(\S+)\s*(.*)'
validate_failures.py:71: SyntaxWarning: invalid escape sequence '\s'
  _VALID_RESULTS_REX = re.compile('([A-Z]+):\s*(\S+)\s*(.*)')
validate_failures.py:82: SyntaxWarning: invalid escape sequence '\.'
  _EXP_LINE_REX = re.compile('^Running (?:.*:)?(.*) \.\.\.\n')
