* examples/fontdumps_n.roff, examples/fontdumps_x.roff: Renamed

to...
* example/fontdumps_n.in, example/fontdumps_x_in: This.
Rename `*fontpath' to `fontpath' and define it conditionally (using
`@fontdir@') so that it can be overridden on the command line.

* Makefile.sub (GENFILES, GENFILES_): New variables for
fontdumps*.roff.
(EXAMPLEFILES): Remove fontdumps.roff.
(CLEANADD): Add GENFILES.
(.in.roff): New rule.
(.SUFFIXES): Add `.in'.
(install_data, uninstall_sub): Updated.
