test: move SPA_NORETURN attributes to header

Otherwise, when building with fortify-headers, I get an error because
the compiler doesn't know pwtest_ptr_notnull will not return if the
passed pointer is null, so it doesn't know the pointer subsequently
passed to memmove via pw_array_remove will be non-null.
