fix syntax warnings in matrix code

[kpedro88]

PR description:

There were a few syntax warnings from the python3 checks (pointed out by @jpata in #32128 (comment)):

src/Configuration/PyReleaseValidation/python/MatrixUtil.py:120: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if len(self.run) is not 0 or self.ls:
src/Configuration/PyReleaseValidation/python/MatrixUtil.py:187: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if len(self.run) is not 0:
src/Configuration/PyReleaseValidation/python/relval_upgrade.py:42: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if (specialType is not 'baseline') and ( ('PU' in step and step.replace('PU','') in specialWF.PU) or (step in specialWF.steps) ):

These are now fixed.

PR validation:

runTheMatrix.py still works.
