Define `fs::hard_link` to not follow symlinks.
POSIX leaves it implementation-defined whether `link` follows symlinks. In practice, for example, on Linux it does not and on FreeBSD it does. So, switch to `linkat`, so that we can pick a behavior rather than depending on OS defaults. Pick the option to not follow symlinks. This is somewhat arbitrary, but seems the less surprising choice because hard linking is a very low-level feature which requires the source and destination to be on the same mounted filesystem, and following a symbolic link could end up in a different mounted filesystem.
