games-fps/freedoom: Add doom engine runtime dependency

Freedoom is distributed by upstream with the intention to be run by a
doom engine; this is also the expectation of end users. This patch adds
a doom engine as a runtime dependency for Freedoom.

Three possible doom engines are listed in RDEPEND: games-engines/odamex,
games-fps/doomsday, games-fps/gzdoom. The games-fps/gzdoom package is
set to preferred as it is the recommendation of the Freedoom upstream
team.
