Subject: 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`.

Fixes: 7b47623b8cae8149 ("perf bench uprobe trace_printk: Add entry attaching an BPF program that does a trace_printk")
