build: Fix powerpc64le target_arch

Starting with version 1.80, the Rust linter does not accept an invalid
value for `target_arch` in configuration checks:

```
   Compiling kata-sys-util v0.1.0 (/home/ddd/Work/kata/kata-containers/src/libs/kata-sys-util)
error: unexpected `cfg` condition value: `powerpc64le`

  --> /home/ddd/Work/kata/kata-containers/src/libs/kata-sys-util/src/protection.rs:17:34
   |
17 | #[cfg(any(target_arch = "s390x", target_arch = "powerpc64le"))]
   |                                  ^^^^^^^^^^^^^^-------------
   |                                                |
   |                                                help: there is a expected value with a similar name: `"powerpc64"`
   |
   = note: expected values for `target_arch` are: `aarch64`, `arm`, `arm64ec`, `avr`, `bpf`, `csky`, `hexagon`, `loongarch64`, `m68k`, `mips`, `mips32r6`, `mips64`, `mips64r6`, `msp430`, `nvptx64`, `powerpc`, `powerpc64`, `riscv32`, `riscv64`, `s390x`, `sparc`, `sparc64`, `wasm32`, `wasm64`, `x86`, and `x86_64`
   = note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration
   = note: `-D unexpected-cfgs` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(unexpected_cfgs)]`
```

According [to GitHub user @Urgau][explain], this is a new warning
introduced in Rust 1.80, but the problem exists before. The correct
architecture name should be `powerpc64`, and the differentiation
between `powerpc64le` and `powerpc64` should use the `target_endian =
"little"` check.
