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.

basehgrc = f.read()
f.close()
