The host distro object was identical to the regular distro objects for a
while now. The constructors in the registry have been aliases to the
base constructors for a long time.
- Deleted all HostDistro constructors from the distributions.
- Changed the supported distro list to only contain base constructor
functions.
- The host distro in the distro registry is a copy of the base distro
that matches the host and does not call a separate constructor.
