Fix the definition of ino_t on 32-bit FreeBSD 12+

Commit 7437d0a erroneously defined it as "ulong" instead of u64.
Nobody noticed the mistake, probably because it was only tested on
64-bit architectures, where those are equivalent.  But it's a problem
now, after rust-lang#3723 , which switched the standard library to a FreeBSD 12
ABI.

Issue rust-lang/rust#130677
