perf tools: Auto-complete for events with ':'
It's a follow up patch for a previous patch "perf tool: Return all
events as auto-completions after comma".
With this patch, auto-completion can work well for events with a ':'.
For example:
root@skl:/tmp# perf stat -e block:block_<TAB>
block:block_bio_backmerge block:block_rq_complete
block:block_bio_bounce block:block_rq_insert
block:block_bio_complete block:block_rq_issue
block:block_bio_frontmerge block:block_rq_remap
block:block_bio_queue block:block_rq_requeue
block:block_bio_remap block:block_sleeprq
block:block_dirty_buffer block:block_split
block:block_getrq block:block_touch_buffer
block:block_plug block:block_unplug
root@skl:/tmp# perf stat -e block:block_rq_<TAB>
block:block_rq_complete block:block_rq_issue block:block_rq_requeue
block:block_rq_insert block:block_rq_remap
root@skl:/tmp# perf stat -e block:block_rq_complete<TAB>
block:block_rq_complete
root@skl:/tmp# perf stat -e block:block_rq_complete
