Fix the definition of "struct stat" on 32-bit FreeBSD 12+

The original definitions were never correct. But nobody noticed because we don't do CI on 32-bit FreeBSD. The problem is apparent now due to #3723 , which caused the nightly toolchain to switch to a FreeBSD 12 ABI. Fixes rust-lang/rust#130677
