Helge Deller fb32effd15 testevdev: Fix detection of word size ...

The check for whether to use a 32- or 64-bit swap for an array of long
values always took the 64-bit path, because <limits.h> wasn't included
and therefore ULONG_MAX wasn't defined. Turn this into a runtime check,
which a reasonable compiler will optimize into a constant.

This fixes testevdev failures on 32-bit big-endian platforms such as hppa
and older powerpc. Little-endian and/or 64-bit platforms are unaffected.
