Subject: [PATCH] selftest: Generate a list of skip entries for SMB1

The following changes prepare the test system so we can generate
the list of tests that fail when SMB1 can no longer be negotiated

1.
Change the values of 'min protocol' set for the various test
environments to be SMB2_02.

Servers will only offer protocols starting with the min specified in the
conf files, we don't need to change the client value here yet (until SMB1 is
truly gone)

2.
The following environments will still negotiate SMB1
   ad_dc_ntvfs, rpc_proxy & s4member

3.
Make test won't stop on first error

Once this patch is applied either
a. Commit to gitlab or
b. Run a private autobuild

For the failing test jobs gather the stdout logs and run the parser

   source4/scripting/devel/test_errors_regrex.py logfile

over the output. This script will generate lines suitable for a
skipfile.

It is a good idea as a final step to say create a file e.g.

    selftest/skip_smb1_fails

and then exclude those tests, running CI with patch similar to wscript
below will verify that the list of tests is complete.
