build: fix hgrc manpage building with docutils 0.9

Since docutils 0.9, `roman` module has been moved from module directory root
(i.e. `site-packages/roman.py`) to `docutils.utils` module. Therefore `import
roman` statement should be wrapped in `try: ... except ImportError: ...` block
to handle importing correctly.

  $ hg init t
  $ cd t
  $ echo a > a
  $ hg add a
  $ hg commit -m test
  $ rm .hg/requires
  $ hg tip
  abort: index 00changelog.i unknown format 2!

  $ echo indoor-pool > .hg/requires
  $ hg tip
  abort: unknown repository format: requires features 'indoor-pool' (upgrade Mercurial)!

  $ echo outdoor-pool >> .hg/requires
  $ hg tip
  abort: unknown repository format: requires features 'indoor-pool', 'outdoor-pool' (upgrade Mercurial)!
