lib: string bug spotted on Solaris.

* lib.c (string_finish): On platforms where we do not
HAVE_MALLOC_USABLE_SIZE, there is a compiler diagnostic.
The code is inappropriately using the set macro and
mkloc to assign the st->st.alloc member, which is just
a number (cnum type), and not a val. The set macro
is only needed when mutating a gc heap object to point to
another gc heap object.
