Subject: [PATCH] ruby: use buildPackages.bison_3_5, fixes cross compilation

Ruby is not compatible with the latest bison version we have so in
458b2cb7d67561c796c6f0660a97eea9b685fc65 I made it use the older 3.5.
This broke cross-compilation. bison is a native build input, so we need
to take it from the `buildPackages` set.
