cache.h: put single NUL at end of struct cache_entry 

Since in-memory index entries are allocated individually now, the
variable slack at the end meant to provide an eight byte alignment
is not needed anymore.  Have a single NUL instead.  This saves zero
to seven bytes for an entry, depending on its filename length.
