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.
