man: sync "JOB FILE PARAMETERS" section with HOWTO

This commit replaces the entire section with the corresponding section
in HOWTO, since the man page is only slightly different from HOWTO
regarding this section.

It also renames the following section names to sync with HOWTO.
  "JOB PARAMETERS" to "JOB FILE PARAMETERS"
  "JOB PARAMETERS"'s sub section "Types" to non-sub section "PARAMETER TYPES"
  "JOB PARAMETERS"'s sub section "Parameter List" to non-sub section "JOB DESCRIPTION"

Since section names aren't following the typical man page convention
(man-pages(7) in Linux) to begin with, changing the section names
to conform to HOWTO does no harm unless there's a reason to keep names
that were once made.
