[PATCH 2/3] perf, tools: Handle completion of upper case events

[Andi Kleen]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Vendor events are often specified in upper case. perf list outputs them
in lower case. Handle this case in perf-completion.sh so that
completion on the upper case events still works.

v2: Use locale aware check for upper case
v3: Use perf list json
