zdtm/static/maps03: don't run for 32-bit

When this test is compiled on ARMv7, we get this:

> maps03.c: In function 'main':
> maps03.c:15:31: error: result of '10l << 30' requires 35 bits
>   to represent, but 'long int' only has 32 bits [-Werror=shift-overflow=]
>  mem = (void *)mmap(NULL, (10L << 30), PROT_READ | PROT_WRITE,
>                               ^~

Surely, the nature of the test looks like it needs 64-bit addressing.
