fortune: remove offensive quotes from build (#171153)

This builds the package with -DNO_OFFENSIVE=true, keeping out the
off (offensive) directory from the resulting fortune files. It
also removes the men-women quotes from the resulting db.

Where various default fortune files include some questionable
quotes, this removes the ones even the upstream finds offensive,
and the men-women category. This is also in line with what Fedora
does:
https://src.fedoraproject.org/rpms/fortune-mod/blob/main/f/fortune-mod.spec#_64-74,
and has done in some capacity for years.
