fix(freebsd): Run cargo fix with more FreeBSD versions

For versions 10, 11, 12, 13, 14, 15, and architectures aarch64, i686,
powerpc64, riscv64gc, and x86_64, I ran the following:

    RUST_LIBC_UNSTABLE_FREEBSD_VERSION=15 cargo fix \
        -Zbuild-std=core \
        --features extra_traits \
        --allow-dirty \
        --edition \
        --broken-code \
        --lib \
        --target aarch64-unknown-freebsd
