default-distrovars.inc: Fix CONNECTIVITY_CHECK_URIS redirect issue

The default CONNECTIVITY_CHECK_URIS uses "https://yoctoproject.org/connectivity.html"
which redirect to "https://www.yoctoproject.org/connectivity.html".

Some network configurations with proxies or restricted internet access
don't handle HTTP redirects properly during the sanity check phase,
causing build failures with:

ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:

Fetcher failure for URL: 'https://yoctoproject.org/connectivity.html'. URL doesn't work.

Updated the default URL to use the final destination directly to avoid
redirect-related connectivity check failures.

Also updated SDK test cases in https.py to use the corrected URL for
consistency.
