Fix TypeError: Can't mix strings and bytes in path components in Tools/Scripts/dump-class-layout

[Tyler Wilcock]

When running the `dump-class-layout` script, I get this error:

$ dump-class-layout -c Release WebCore Pair
Traceback (most recent call last):
  File "/home/twilco/projects/webkit/Tools/Scripts//dump-class-layout", line 88, in <module>

I think the right answer here is to fix webkit_build_dir() and do the decode subprocess.check_output, it seems like that function should return a string, not bytes.
