perf tools: Fix the bash completion to support listing events for --event

Browse Source 
The bash completion only supports -e rather than --event, so fix it.

Example:

Before this patch:

 $ perf record --event <TAB>
 $

As shown above, the events of record does not come out.

After this patch:

 $ perf record --event <TAB>
 lignment-faults                   cpu/instructions/
 L1-dcache-prefetch-misses          node-prefetches

 L1-icache-load-misses              node-stores
 uncore_rbox_0/qpi1_idle_filt/
 ...

As shown above, the events of record can come out now.
