linux: drop `*_latest_hardened`-attributes in favor of versioned attributes

The problem behind this is that the hardened patchset[1]. Quite recently
this led to a weird problem when Linux 5.12 was dropped (and thus had to
be removed from `nixpkgs`), there were no patches for 5.13, so
`linuxPackages_hardened_latest` had to be downgraded to 5.10 as base[2]
which may be rather unintuitive and unexpected.

To avoid these kind of "silent downgrades" in the future, it makes sense
to drop the attribute entirely. If somebody wants to use a hardened
kernel, it's better to explicitly pin it using the newly introduced
versioned attributes, e.g. `linuxPackages_4_14_hardened`.
