cpan-base: set default UPSTREAM_CHECK_REGEX

as cpan release versions are almost always follow an a.b version scheme,
it's better to filter out beta releases such as a.b.c.
Use the first resource fetched from https://cpan.metacpan.org as base
for calculating the needed regex.
In case nothing can be calculated fall back to nothing.
Add this to cpan-base to enable it for new & old style cpan integration.
