9d25ccf0e8 Change built-in kernel targets to be os = none throughout
Whether for Rust's own `target_os`, LLVM's triples, or GNU config's, the
OS-related have fields have been for code running *on* that OS, not code
that is *part* of the OS.

The difference is huge, as syscall interfaces are nothing like
freestanding interfaces. Kernels are (hypervisors and other more exotic
situations aside) freestanding programs that use the interfaces provided
by the hardware. It's *those* interfaces, the ones external to the
program being built and its software dependencies, that are the content
of the target.

For the Linux Kernel in particular, `target_env: "gnu"` is removed for
the same reason: that `-gnu` refers to glibc or GNU/linux, neither of
which applies to the kernel itself.

Relates to #74247

Thanks @ojeda for catching some things.

9d952cbe95 unwind: Move linux-gnu library linking to lib.rs and libc
This unifies it with the handling of `target-feature=+crt-static` on
other platforms, and allows for supporting static glibc in the future.
