build: Fix missing install of man page in certain environments

build: Fix missing install of man page in certain environments

It turns out the logic for dist_man_MANS was incorrectly put inside the
HAVE_PYDOCUTILS block.  This results in the man page being installed
only if python-docutils is installed and available.

The solution is simple, move the dist_man_MANS part outside the
python-docutils block.  The openvpn.8 file is prebuilt in source
tarballs and will thus be available.
