bug#35239: 27.0.50; Some gnus-msg.el variables are unused

[Basil L. Contovounesios]

Severity: minor
Tags: patch

The user options gnus-debug-files and gnus-debug-exclude-variables have
been unused since Emacs 24.1[1].  The following patch marks them as
obsolete, fixes a few custom :types, and also removes the unused
variable gnus-check-before-posting.  WDYT?
