make mono a build time only dependency
mono is a build-time only dependency, not actually a runtime one. This appears
to require changing /usr/ports/Mk/Uses/mono.mk to do this, as the normal USES=mono:build doesn't help:
foundationdb> make run-depends-list
foundationdb> make build-depends-list
The patch for FDB is trivial, but needs mono fixed first - PR underway for that too.
