ANDROID: GKI: add vendor padding variable in struct sock

Browse Source 
Some vendors want to add things to 'struct sock', so give them a u64
where they can then have a pointer off to their private data and they
can do whatever they want to do without breaking or changing any abi for
anyone else.

Note, usually an android trace hook is also needed to use this properly,
so be aware that this will be required as well.
