[RFE] Add dnf builddep --with bcond

[pemensik]

I have in my bind package few dependencies, which are by default not needed for normal build. Because they are needed only when --with SYSTEMTEST is used. I would like dnf builddep to have also --with bcond and --without bcond offered for dnf builddep *.spec.

That might help when I want to do additional testing on top of build and that needs extra dependencies, varying between different versions. Similar to what rpmbuild offers. I have found I can add -D _with_SYSTEMTEST, but that is hackish and not user friendly. It requires me to know how bcond_with works internally.

FYI builddep is part of the dnf-plugins-core. I've already opened RFE for that
rpm-software-management/dnf-plugins-core#521

Oh, I knew that is done by plugin, but thought those plugins are part of this repository too. That means it can be closed here.

Just please add +1 in that RFE 😋
