Fix errors on the recently added kernel PMDAs man page
Fix errors on the recently added kernel PMDAs man page

There is a separate pmdaproc man page, so listing that here
gives warnings ("file listed twice") during packaging phase.
Also, "kernel PMDA" is too generic a term to use in the NAME
section as 'apropos kernel' then hits on this man page - fix
that as well.
