[PATCH 1/2] trace-cmd: Use "exists" instead of "exist"

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

As a native English speaker, I find that the words "file_exists" and
"dir_exists" sounds better to the ear than "file_exist" and "dir_exist".
As "exist" is for the plural, and "exists" is for the singular.
