[Buildroot] [PATCH 1/1] support/testing/run-tests: add a nose2 debug option

[Julien Olivain]

This commit adds the -D/--debug command line options to the
support/testing/run-tests script.

Using one of those options will pass "--log-level debug" to the
nose2 invocations. This can be useful to debug nose2 internal
behaviors. See:
https://github.com/nose-devs/nose2/blob/0.15.1/nose2/main.py#L209

For example, calling:

    support/testing/run-tests --list --debug

will output:

    List of tests
    DEBUG:nose2.main:logging initialized debug
    ...

For info, this patch was written for a small investigation asked by
Thomas in the discussion at:
https://lists.buildroot.org/pipermail/buildroot/2024-August/759983.html
This debug option might be useful in some other cases...
