Fix python scripts in src/webkit

Fix python scripts in src/webkit

Make sure that:
- shebang is only present for executable files
- shebang is #!/usr/bin/env python
- __main__ is only present for executable files
- file's executable bit is coherent

Also fix EOF LF to be only one.

lgtm, but I bet we can delete a bunch of these files.

I bet this file isn't even used any more ... I'll ping Ojan to see.

I bet this can go, too.
