benchmarks: add unixbench

Add a recipe for UnixBench, a benchmark suite used to measure
CPU, memory, and overall system performance.

The recipe has been successfully built and validated on
aarch64 targets. Functional testing confirmed that the
benchmark suite executes correctly and generates results.

+Subject: [PATCH] Skip make checks for prebuilt Yocto package
+
+The UnixBench Run script expects a source tree and invokes
+'make check' and 'make all'. In Yocto, binaries are prebuilt
+during do_compile() and only runtime artifacts are installed.
+Skip the build verification step.
+
+Upstream-Status: Inappropriate [cross-compilation]
