perf tools: Complete tracepoint event names
Currently tracepoint events cannot be completed because they contain a
colon (:) character. The colon is considered as a word separator when
bash completion is done - variable COMP_WORDBREAKS contains colon - so
if a word being completed contains a colon it can be a problem.
Recent versions of bash completion provide -n switch to
_get_comp_words_by_ref and __ltrim_colon_completions functions in order
to resolve this issue. Copy the latter in case not exists.
