Arch Linux

Description: Hi facter with our minimal vagrant images looks like this:

```
2020-09-27 21:31:28.068760 WARN puppetlabs.facter - could not locate a ruby library: facts requiring Ruby will not be resolved.

this is latest facter:

after installing ruby:

```
# facter os
{
architecture => "x86_64",
family => "Archlinux",
hardware => "x86_64",
name => "Archlinux",
release => {
full => "5.7.12-arch1-1",
major => "5",
minor => "7"
},
selinux => {
enabled => false
}
}
```

one could now argue if it's a soft-dep or not. In my opinion it's a hard one because facters throws an error

besides ruby, there is also lsb-release missing. there is currently no distro hash in the facter output. But puppet assumes it's always there. It appears after installing lsb-release:

```

# facter os
{
architecture => "x86_64",
distro => {
codename => "n/a",
description => "Arch Linux",
id => "Arch",
release => {
full => "rolling",
major => "rolling"
},
specification => "1.4"
},
family => "Archlinux",
hardware => "x86_64",
name => "Archlinux",
release => {
full => "5.7.12-arch1-1",
major => "5",
minor => "7"
},
selinux => {
enabled => false
}
}
```

tl;dr please add ruby and lsb-release as runtime dependencies to facter.


cheers, Tim
