Documentation/trace/uprobetracer.txt: fix incorrect examples
Current uprobetracer examples don't work as they use an incorrect syntax
- if no event name is specified then 'p/r' must not be followed by a
colon
- if no event name is specified then the default event name will have a
'p_' prefix, so use that in the '-' example as well
