[PATCH] perf tool: Auto-complete for the event with ':'

[Jin Yao]

It's a follow up patch for a previous patch "perf tool: Return all
events as auto-completions after comma".

Sorry about that, I should send these 2 patches in a patch-set.

With this patch, the auto-completion can work well for the event
with ':'. 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
