When running "make pkg-stats" on a host with Python 3.14 (e.g.
Fedora 43 for example), the execution fails with the error:

    Checking URL status
    Traceback (most recent call last):
      File "/buildroot/support/scripts/pkg-stats", line 1387, in <module>
        __main__()
        ~~~~~~~~^^
      File "/buildroot/support/scripts/pkg-stats", line 1368, in __main__
        loop = asyncio.get_event_loop()
      File "/usr/lib64/python3.14/asyncio/events.py", line 715, in get_event_loop
        raise RuntimeError('There is no current event loop in thread %r.'
                           % threading.current_thread().name)
    RuntimeError: There is no current event loop in thread 'MainThread'.

This is due to a breaking change introduced in Python 3.14
asyncio.get_event_loop(). See [1]. Before Python 3.14, this call was
creating and setting an event loop if there was none. This situation
is now a runtime error.

In order to fix this issue with newer Python version, while keeping
backward compatibility, this commit replaces the code:

    loop = asyncio.get_event_loop()

by an explicit event loop creation:

    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)

This commit was tested on a Fedora 43 host with Python-3.14.2, and
with the Buildroot Docker image plus the python3-aiohttp package
which is a Debian 12 with Python-3.11.2.
