Fix add-probe command syntax without --add option.
perf-probe supports add-probe command without --add
option. But it treats each argument as an event definition.
e.g.

perf probe func arg1 arg2

 is interpreted as

perf probe --add func --add arg1 --add arg2

But it may be useless in many cases.

This patch fixes this syntax to fold those arguments into
one event definition if there is no --add option. With this
change, above command is interpreted as below;

perf probe --add "func arg1 arg2"
