GHA: add DragonFlyBSD workflow (#39)

* GHA: add DragonFlyBSD workflow

* GHA: do dragonflybsd check on push, pr

* dragonflybsd: use dev version of debug-shell

* dragonflybad: run debug shell earlier

So it runs if other steps error.

* Need dev fs on DragonflyBSD

* Fix compilation on DragonFlyBSD

* Need dev openssl on GHA for DragonFlyBSD

* dragonfly GHA: need to ignore spelling

It depends on Rcpp, which fails to install.
We don't need the soft dependencies of fs, anyway,
but have no way of expression this currently.

* DragonFly: fix remote in GHA workflow

* GHA dragonfly: ignore sodium as well

Not needed, has system dep.
