Subject: [PATCH] perf tools: Remove extra '/' character in events file path

The array debugfs_known_mountpoints[] will cause extra '/'
character output.
Remove it.

pre:
$ perf probe -l
/sys/kernel/debug//tracing/uprobe_events file does not exist -
please rebuild kernel with CONFIG_UPROBE_EVENTS.

post:
$ perf probe -l
/sys/kernel/debug/tracing/uprobe_events file does not exist -
please rebuild kernel with CONFIG_UPROBE_EVENTS.
