perf probe: Support distro-style debuginfo for uprobe
Support distro-style debuginfo supported by dso for setting uprobes. Note that this tries to find a debuginfo file based on the real path of the target binary. If the debuginfo is not correctly installed on the system, this can not find it. Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: David Ahern <dsahern@gmail.com> Cc: "David A.
