Tests: workaround GCC 4.4.3 warning reported for list_atomic.c 'val'

* tests/list_atomic.template (XSIZE_list_atomicXX): Use "static"
modifier for "val" local variable to initialize it (cannot use direct
assignment to zero because "val" type could be a SIMD vector type if
XCTYPE is AO_double_t) to workaround GCC v4.4.3
"'val' is used uninitialized in this function" warning reported for
AO_load.
