tracing/uprobes: Rename uprobe_{trace,perf}_print() functions

The uprobe_{trace,perf}_print functions are misnomers since what they
do is not printing.  There's also a real print function named
print_uprobe_event() so they'll only increase confusion IMHO.

Rename them with double underscores to follow convention of kprobe.
