[PATCH] trace-cmd split: Do not append '.1' to single file if output specified

[Steven Rostedt <rostedt@goodmis.org>]

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

If the user specifies an output file, and it is not the same as the input
file, and the '-r' (repeat) option is not specified, there's no reason to
append the '.1' to the output file name. Just use what the user specified.
