python: Fix nroff indentation for <dl> after <hN>.
When XML is used for writing manpages, in the case that there is a
header tag followed by <dl>, the nroff python utility indents the <dl>
tag (and children) an extra level which is unnecessary and makes the
formatting inconsistent between manpages written directly in nroff vs
manpages written in XML and converted to nroff. Fix the indentation by
removing the extraneous .RS / .RE tags added to generated nroff in this
case.
This fixes the formatting of ovn/utilities/ovn-nbctl.8 man page.
