struct: recycle conses used for slot lookups.

When a slot is not found in a cache, and in other situations
the object system conses up a key in order to search a the
global slot_hash. We should be recycling these keys
for reuse via rcyc_cons. This change makes recompilation of
TXR's library (make clean-tlo; make) about 1.6% faster.

* struct.c (lookup_slot, lookup_static_slot_desc, static_slot_p):
Recycle the hash key cons cell via rcyc_cons, so it can be
reused immediately.
