Subject: kunit: tool: properly report the used arch for --json, or '' if not known
X-Git-Tag: v6.1-rc5~1277^2~28

kunit: tool: properly report the used arch for --json, or '' if not known

Before, kunit.py always printed "arch": "UM" in its json output, but...
1. With `kunit.py parse`, we could be parsing output from anywhere, so
    we can't say that.
2. Capitalizing it is probably wrong, as it's `ARCH=um`
3. Commit 87c9c1631788 ("kunit: tool: add support for QEMU") made it so
   kunit.py could knowingly run a different arch, yet we'd still always
   claim "UM".

This patch addresses all of those. E.g.

1.
$ ./tools/testing/kunit/kunit.py parse .kunit/test.log --json | grep -o '"arch.*' | sort -u
"arch": "",

2.
$ ./tools/testing/kunit/kunit.py run --json | ...
"arch": "um",

3.
$ ./tools/testing/kunit/kunit.py run --json --arch=x86_64 | ...
"arch": "x86_64",
