    perf bench uprobe: Remove lib64 from libc.so.6 binary path
    
    [ Upstream commit 459fee7b508231cd4622b3bd94aaa85e8e16b888 ]
    
    bpf_program__attach_uprobe_opts will search LD_LIBRARY_PATH and so
    specifying `/lib64` is unnecessary and causes failures for libc.so.6
    paths like `/lib/x86_64-linux-gnu/libc.so.6`.
