commit 18d597038bca372c9bc6210f5bcfdc711cde4dba

bootstrap.sh now installs nix & home-manager

- fedora: install nix (if not present), then home-manager
- nixos: install home-manager

Under fedora (non-nixos), disable manpath from home-manager, otherwise
using any nix binary will end up failing really hard (and killing the
machine too…)
