Link the new hotswap rewriter against the LLVM dylib, like the rest of comgr.

ROCm 10.0 adds src/hotswap/rewriter, which resolves its LLVM dependencies with
an unguarded llvm_map_components_to_libnames(), yielding per-component static
library names (-lLLVMAMDGPUDesc, -lLLVMMCDisassembler, ...). Distributions that
build LLVM as a single shared library do not ship those, so the link of
libamd_comgr.so fails with:

    ld: cannot find -lLLVMAMDGPUDesc: No such file or directory
    ld: cannot find -lLLVMAMDGPUDisassembler: No such file or directory
    ld: cannot find -lLLVMAMDGPUInfo: No such file or directory

comgr's own top-level CMakeLists.txt already handles this correctly at line
554 with an `if (LLVM_LINK_LLVM_DYLIB) set(LLVM_LIBS LLVM ...)` branch; the new
subdirectory simply did not copy it. Apply the same idiom so both link paths
stay consistent.
