[PATCH v1] kunit: tool: add 'mte=on' qemu arg on arm64

From: Paul Heidekrüger
Date: Fri Feb 23 2024 - 16:08:15 EST


Tests relying on the ARM Memory Tagging Extension (MTE) may crash when
the corresponding qemu option, which is available since qemu 6.2, is not
explicitly passed to kunit_tool via the command line.

To make life easier, enable MTE by default for kunit_tool's arm64
qemu config.
