Revert "Make hidepip when pig configurable via a skin attribute"

This reverts commit 37a17830f2c5ec22fc17c56e64b7461e3cd6e731.

As I found a more easy solution via self.skinAttributes
Make hidepip when pig configurable via a skin attribute

With the attribute hidePip="0" you are able in a skin to disable the new
hide Pip when Pig function. see

example:
<widget source="session.VideoPicture" render="Pig" position="25,98" size="440,248" backgroundColor="transparent" zPosition="2" hidePip="0"/>
