hamt tests: Fix compilation error with AIX xlc

[Bruno Haible]

Compiling a testdir on AIX 7.1 with xlc, I get this compilation error:

source='test-hamt.c' object='test-hamt.o' libtool=no  DEPDIR=.deps depmode=xlc 
/bin/sh ../build-aux/depcomp  xlc -q64 -qthreaded -qtls -DHAVE_CONFIG_H

"test-hamt.c", line 351.43: 1506-196 (S) Initialization between types "struct 
hamt*" and "struct hamt_iterator" is not allowed.
make: 1254-004 The error code from the last command is 1.

This patch fixes it.
