In golang 1.24+ sha1 signing is not allowed anymore, and a lot of certs in various testdata directories are SHA1 signed. There are also expired certs, that all together make the test suite fails in a lot of way.

I used various AI tools to do the following:

  1. Create reliable build_certs.sh scripts able to regenerate the certs data, documenting how they are related to each other and what are the constraints that tests expect.
  2. Regenerate all the testdata dirs to make the test suite completely pass on golang 1.24+.

Given how old sha1 signing is, I would really vote to get rid of it as a special use case and focus on golang 1.24+ compatibility.

Fixes: #1413 1413

Add scripts to generate all the certs material under the various
testdata directories, together with comments about how they are related
with each other. The idea is to be able to programmatically control and
regenerate the data when needed (certs expired, shaXXX deprecation, ..).

The current issue is that most of the certs are expired or signed
with SHA1, that is not allowed anymore by golang 1.24+.

The x509sha1 GODEBUG setting has been removed with go1.24, tests relying on sha1 certificates will fail when running with >= go1.24
