Remove useless version wildcard from CONFLICTS entries

[se]

Summary

The matching for conflicts performs a file glob style match of the patterns first with the package name without version (i.e. as reported by "pkg query "%n") and then against the full package name ("%n-%v").

It has been common practice to use patterns like "bash-[0-9]*" to match all versions of bash packages, for example, and to not match bash-completions, as "bash-*" would do.
But a pattern of just "bash" will have exactly the same effect as "bash-[0-9]*" due to the way, the check has been implemented.

This review contains patches for all ports that have CONFLICTS entries redundantly ending in "-[0-9]*" and removes that version wildcard.

If portmgr agrees, these CONFLICTS could be simplified in one go.
Else I could generate (hundreds) of reviews for the individual port committers to approve.

Since this patch is against the ports tree as of 2021-10-28 13:00:00 UTC and so many ports are affected, it might become partially stale within a few days or weeks.
I'm of course willing to rebase the patch as requireed, if I get approval to commit these changes.

Test Plan

Apply patches and verify that they still lead to identical conflicts check results.
This has been done on a subset of the affected ports after generating the patch with the expected (correct) outcome.

You don't need portmgr validation for that this is part of the cleanup blanket ;)
