freebsd32: fix types on statfs syscalls
Rename struct statfs32 to struct ostatfs32 to mirror struct ostatfs. These structs are use for COMPAT4 support. Stop using struct statfs32 for modern implementations as struct statfs uses fixed-width types and it the same on all architectures. Reviewed by: kevans
