Change WL_ZOMBIE_OBJECT from 0x2 to an actual pointer

Browse source 
In order to use the second-lowest bit of each pointer in wl_map for the
WL_MAP_ENTRY_LEGACY flag, every pointer has to be a multiple of 4.  This
was a good assumption, except with WL_ZOMBIE_OBJECT.  This commit creates
an actual static variable to which WL_ZOMBIE_OBJECT now points.  Since
things are only every compared to WL_ZOMBIE_OBJECT with "==" or "!=", the
only thing that matters is that it is unique.
