Subject: [PATCH] perf parse-events: Ignore case in topdown.slots check

An issue with icelakex metrics:
https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/tree/tools/perf/pmu-events/arch/x86/icelakex/icx-metrics.json?h=perf/core&id=65eab2bc7dab326ee892ec5a4c749470b368b51a#n48
That causes the slots not to be first.

Fixes: 94dbfd6781a0 ("perf parse-events: Architecture specific leader override")
