dev-util/perf/files/5.15-Add-vmlinux-in-perf-inject.patch

Subject: [PATCH 3/3] perf inject: Add vmlinux and ignore-vmlinux arguments

Other perf tools allow specifying the path to vmlinux. 'perf inject'
didn't have this argument which made some auxtrace workflows difficult.

Also add --ignore-vmlinux for consistency with other tools.
