Subject: [PATCH 1/3] rust: pin-init: internal: skip rustfmt formatting of kernel-only module

The `quote` module only is available in the kernel and thus running
`cargo fmt` or `rustfmt internal/src/lib.rs` in the user-space
repository [1] results in:

    error: couldn't read `~/pin-init/internal/src/../../../macros/quote.rs`: No such file or directory (os error 2)
      --> ~/pin-init/internal/src/lib.rs:25:1
       |
    25 | mod quote;
       | ^^^^^^^^^^

    Error writing files: failed to resolve mod `quote`: ~/pin-init/internal/src/../../../macros/quote.rs does not exist

Thus mark it with `rustfmt::skip` when compiling without kernel support.
