[python][rfc] Remove unused value_object attribute `owned_by_gdb'.

[Thiago Jung Bauermann <bauerman at br dot ibm dot com>]

Hi,

I noticed that the owned_by_gdb element in value_object can only be set
to 0 in the current code. Is this a remnant of some dropped effort? Any
reason not to commit this patch?

I'll commit it in a few days if no one comments...
