print/foo2zjs: Remove bad dependency check of dc

The package assumes that if the dc program doesn't support -V, it must
not support -e either.  This is a bad assumption; DragonFly supports
-e but doesn't support -V.  Rather than try to fix a bad conftest, just
remove it completely.  There's a previous test for dc presence.  If dc
doesn't support -e, let it break during the build rather than before it.
It doesn't take long to build.
