lmstudio: remove unnecessary --set-rpath from patchelf to fix lms segfault

[cavebatsofware]

Closes #510446

As described in #510446, the lms CLI tool segfaults due to an unnecessary --set-rpath argument being passed to patchelf.

The lms binary is a Node.js/webpack bundle that doesn't require custom library paths. Setting rpath on NixOS can cause ELF header corruption leading to segmentation faults. Only the interpreter needs fixing for AppImage-extracted binaries.

Removing the --set-rpath argument resolves the issue while keeping the necessary --set-interpreter fix.

Before (broken):

patchelf --set-interpreter "${stdenv.cc.bintools.dynamicLinker}" \
  --set-rpath "${lib.getLib stdenv.cc.cc}/lib:${lib.getLib stdenv.cc.cc}/lib64:$out/lib:${
    lib.makeLibraryPath [ (lib.getLib stdenv.cc.cc) ]
  }" $out/bin/lms

After (fixed)

patchelf --set-interpreter "${stdenv.cc.bintools.dynamicLinker}" $out/bin/lms

Thank you for the fix!

I do note that while this removes the segfault, I was unable to get lms serve to run. How is it on your end?

Server appears to be working on my side, my package repo is pointed at my forks master which has this merged in already, so it may be something with it running from shell vs a system package but I don't know for sure if that is why it isn't working for you.
