[Groff] site-dependent font directory

[Werner LEMBERG]

>From the NEWS file:

o A local font directory has been prepended to the default font path; it
  defaults to /usr/local/share/groff/site-font.  Similar to the normal
  font searching process, files must be placed into a devXXX subdirectory,
  e.g.

    /usr/local/share/groff/site-font/devps/FOO

  for a PostScript font definition file FOO.
