groff: not ship /usr/bin/glilypond

Not ship /usr/bin/glilypond and related files such
as man file /usr/share/man/man1/glilypond.1 and other
three files related to glilypond under
/usr/lib/groff/glilypond in embedded system, it is because:

- Remove the confusion about glilypond fails to run
  because it lacks dependency on File::HomeDir perl
  module

- We don't often have need for sheet music conversion
  in groff in embedded or IoT devices (glilypond
  transforms sheet music written in the lilypond language
  into the groff language using the .PSPIC request, such
  that groff can transform it into a format that can be
  displayed directly).
