lib: don't GC-protect two non-heap objects.
* lib.c (obj_init): The null string literal and "nil" do not
require gc protection; they cannot be reclaimed by the garbage
collector, which ignores them. Don't waste two slots in the
prot_stack on them. This is a remnant from ancient TXR;
these variables were protected already in Version 11 from
September 2009. At that time, there were no built-in string
literal objects; these two objects were heap-allocated.
