D5995: Fix CompilerFilterStrategy::errorInLine() to handle paths with whitespace

[Friedrich W. H. Kossebau]

REVISION SUMMARY
  The "([^: \\t]+):" does not match strings with white space. While this
  reduces the chance of wrong matches, it also excludes valid ones for
  paths with white space in them (like on new KDE CI).
  
  The different regex for the different tools are a bit inconsistent on that
  matter, so as consistent solution whitespaces in paths are supported.
  
  Separate commit for the fixes of the missing double escape for \t (?)

TEST PLAN
  test_filteringstrategy no longer fails when sources are below a path
  with white spaces. And cmake/gcc errors in projects with such paths
  are now also properly supported.
