perf list: Make vendor event matching case insensitive
Make the 'perf list' glob matching for vendor events case insensitive.
This allows to use the upper case vendor events with perf list too.
Now the following works:
% perf list LONGEST_LAT
...
cache:
longest_lat_cache.miss
[Core-originated cacheable demand requests missed LLC]
longest_lat_cache.reference
[Core-originated cacheable demand requests that refer to LLC]
