maint: Ignore all intermediate and generated man pages

Since commit 9b77ce63f1d7 we create a .in file while building all
man pages, including those in the tools/ directory; update the
ignore patterns to take this change into account.

The new ignore patterns are generic enough that we can get rid of
a few existing ones as well.
