From: Masami Hiramatsu (Google) <mhiramat@xxxxxxxxxx>
Make add_remove_uprobe test case more robust against various real
binary name.
Current add_remove_uprobe.tc test expects the real binary of /bin/sh
is '*/bin/*sh', but it does not work on busybox environment.
Instead of using fixed pattern, use readlink to identify real binary
name.
