Avi Kivity 07c5edcc30 tools: add patchelf utility ...

We use patchelf to rewrite the dynamic loader (known as the interpreter)
of the binaries we ship, so we can point to our shipped dynamic loader,
which is compatible with our binaries, rather than rely on the distribution's
dynamic loader, which is likely to be incompatible.

Upstream patchelf losing compatibity [1] with Linux 5.17 and below.
This change was also picked up by Fedora 42, so we cannot update the
toolchain to that distribution until we have an alternative.

Here we add a minimal patchelf alternative. It was mostly written by
Claude. It is minimal in that it only supports --set-interpreter and
--print-interpreter, and works well enough for our needs. We still use
the original patchelf for --remove-rpath; this reduces our maintenance
needs.
