compat netbsd32 dev_t alignment fixes

[Nicolas Joly <njoly%pasteur.fr@localhost>]

Hi,

Attached a small patch that fix some dev_t alignment problems under
compat netbsd32. Now that dev_t is a 64bit value, we cannot use it
directly anymore but rather netbsd32_uint64 (with 32bit alignment)
instead.

This fix some program crashs when using all stat(2) family
functions...

Ok to commit ?
